I try to download the dislin library but it does not work , any of the files in the mentioned site can not be downloaded .
May because of Ftp download .
does the downloads work properly ?
I want this one :
ftp://ftp.gwdg.de/pub/grafik/dislin/windows/dl_91_if.zip
edit : I finally downloaded the files .

Did you know?
Doug Currie has written an extension of Dislin for the programming language Lua. The extension is available from the site http://luaforge.net/projects/ldislin.

ok I installed the DISLIN library , but :
when I run the following test program I will recieve some errors

PROGRAM TEST
USE DISLIN
CALL DISINI ()
CALL MESSAG ('This is a test', 100, 100)
CALL DISFIN ()
END PROGRAM TEST

error:
error : unresolved external symbol _DISINI referenced in function _MAIN__
and the same error with the MESSAG and DISFIN and any other statements that I try.

it seems that the library is added to the project but the statements does not work!

can anyone help me ?
please illustrate How to add the environment variables to the win XP
I have added the variables to the Control Panel -> Sytem -> Advanced ->Environment variables , but I,m not so sure if it done properly .
Name :DISLIN
Value : C:dislin\win

I have tested the DISLIN for DIGITAL visual fortran 6 and
also with MS visual Studio 2005 with Intel visual fortran Compiler Pro 9.1
and I used the proper DISLIN library for each compiler .
but ...

One of my friends gave me "Visual fortran compiler pro 9.1 with IMSL" as a gift . but It require "visual studio 2002 or 2003 ".
I wanna to know that if I provide the visual studio and if I install the fortran compiler , can I run and compile the Fortran 90 files through the visual studio ?

I can't answer your question, it's too Window$-related for me, and I don't use that virus pretending to be an "operating system". However, I have a recommandation. Why don't you try the Eclipse project callled Photran (sic)? It provides a powerful IDE, which is able to use virtually any Fortran compiler, plus it's free. It works fine even in Window$, it just need a recent Java Developement Kit (JDK), which is also free ;).

Also I need a good book for Fortran Programming .Any recommendation ?

IMHO, the best book about pure Fortran 95 is this:
T. M. R. Ellis and Ivor R. Philips, Programming in F, Addison-Wesley 1998.
It teaches you how to write programs in "F", which is a subset of Fortran 95, where old, obsolete features are removed, and considered as syntax errors. As a result, using F, you must write structured, fully module-oriented programs. However, this also means that old (and well-working) codes you can find in the Internet won't work with an F compiler (well, they work, but not trivially). However, any F program works with any Fortran 95 compiler, so I suggest to learn F, even if you use a Fortran 90/95 compiler.
A best seller on Fortran Numerical Analysis programming is Numerical Recipes in Fortran 90 (the on-line PDF version is here). However, I don't really suggest that book. It contains a lot of ready-to-work libraries on many Numerical Analysis topics, but you can find much better libraries in the Internet sites I have posted recently. I know many people how are "stucked": they always use Numerical Recipes, so they are missing much more powerful algorithm implementations which can be easily found for free.

Did you know?
Doug Currie has written an extension of Dislin for the programming language Lua. The extension is available from the site http://luaforge.net/projects/ldislin.

Nice to know, but, for god's sake, why do I need to use DISLIN with Lua in my PC?
In a real PC, Lua is good for writing World of Warcraft maps, and generally things like that. It is certainly a bad choice for numerical programming. On the other hand, in ClassPad, CPLua is an excellent choice for programming; in fact, CPLua is the only well-working choice, since the other option you have is to use... CPBasic.

error : unresolved external symbol _DISINI referenced in function _MAIN__

This error message means that the compiler cannot find the DISLIN libraries. Are you sure you have installed DISLIN correctly? Try to add the DISLIN directory to the PATH. The last time I did that in Window$ is several years ago, but I think I remember well: in a command-line window, type
PATH=<your DISLIN path>;%PATH%
then start Fortran from the command line (you can just write a "batch" file doing all this).

I could compile the file.But :
I think I have some problems with the environment variables .
I think I can not define them in the win XP properly.
the statement you mention above is for win 98 , me .
for win xp I should use the control panel -> system -> environment variables:
here there is 2 parameter :
Variable Name ,Varable value
I choosed :Variable Name :DISLIN , Variable value : path for installation
but When I run the program ,
there is this error :"the application has failed to start because disdll.dll was not found . Re installing the application may fix the problem"
I copy, pasted the disdll.dll file to the "Windows\system32" Folder and the program run but without any output.
Just : "End of the DILIN 9.1 Library" will be printed on the screen.
For example :I tested the curve and surface Fortran 90 example code on the disline.de site but no curve will be ploted on the screen.

I messaged Helmut Michels and he said that :
"Dislin creates by default a plotfile. If you want to plot to the screen,
you have to include the statement CALL METAFL('CONS') before DISINI."

and now the dislin works properly.
thanks to you and to Helmut Michels.

What is the newest LuaNum version?
Where is the latest version download link?
Btw, Is it an Open Source program?
I'm going to learn it within next week.
How can I found some training materials
(something like PowerPont presentation or ...) about it?

What is the newest LuaNum version?

LuaNumAn was renamed to LNA several months ago (topic's name is still LuaNumAn because I cannot change it (perharps a modulator can do that for me? [*]).
Anyway, LNA's latest version is 1.60, released June 12, 2006. Note that version 1.70 is almost ready, but I didn't released it yet, due to lack of time...
You will always find information about the latest version at LNA's initial post (here).

Where is the latest version download link?

Here is LNA 1.60 and here is its documentation.

Btw, Is it an Open Source program?

Yes, in terms of the GNU General Public License (GPL). If you plan to modify LNA's source code, you should first carefully read GPL (it is included in LNA's documentation).

I'm going to learn it within next week.

It's not difficult to learn LNA, but you will need to spare some of your free time. You need to know CPLua before starting. If you plan to learn LNA in one afternoon, you will be probably disappointed.

How can I found some training materials (something like PowerPoint presentation or ...) about it?

The documentation is the first place to go. Please read the documentation before doing anything else :r-t-f-m: . It includes many explanations and examples. After that, the best "training material" is practicing. Practice makes perfect ;).
Btw, You will never find training material in PowerPoint presentation or Word document, at least not written by me. Reason: I don't like and I don't use Micro$oft products.

P.S. Maybe I need to add a "FAQ" in LNA's documentation.

Hallo!

I'm writing a function for the QR decomposition but I think that my Idea has too many for loop!

Is there a quickly solution to compute a matrix operation like this (hous_mult is a function that return a (k-n)x(k-n)-Matrix):
A(k : n, k : n) = house_mult(A(k : n, k : n), v(k : n))

My idea is to use a fro loop to build A(k : n, k : n) with the function LNAutils/Part, save the result of house_mult in a temporary matrix and then copy it to my matrix A. Do you have an other idea?

I need more information concerning your house_mult function (what it does, and how it does it).
Btw, you can use LU decomposition instead of QR decomposition. LU decomposition is already implemented in LNA, and has been passed several tests succesfully.

Of course it is possible... but I don't think I will have the time to do it in the near future. Note that LNAplot already supports animated and windowed graphics, and vector plots. All that is implemented in LNA 1.70, but I haven't released that version yet, simply because I don't have time to write a decent documentation for the new features :(

Hi, first of all, thank you Orwell and PAP. CPLua AND LNA are the solution to my problems. :D

PAP, I know that you are occupied, but, when will we be able to have the LNA 1.7 in our classpad's? The LNA 1.6 is very useful, I cannot wait to know what us brings the LNA 1.7

A suggestion: to improve the function MatPrint, since when the number of columns is too big, we cannot estimate the complete Matrix; if it is not possible to do in the window Console, a good idea would be to do it in a window created with UI package. :nod:

PD: sorry for my poor English.

Thank you for your kind compliments :)

PAP, I know that you are occupied, but, when will we be able to have the LNA 1.7 in our classpad's?

I don't really know, and I don't want to announce release dates, since I did it in the past, and I failed due to the lack of time. However, if I were to guess, I'd say within July.

The LNA 1.6 is very useful, I cannot wait to know what us brings the LNA 1.7

In short, LNA 1.7 new features include multiple "window" plots, vector graphics, animated plots, and a few new numerical methods.

A suggestion: to improve the function MatPrint, since when the number of columns is too big, we cannot estimate the complete Matrix; if it is not possible to do in the window Console, a good idea would be to do it in a window created with UI package. :nod:

That's a good idea... UI could also be used to implement "windowed" plots etc. I thought about this, I did some experiments with the UI package, but I can't tell I liked it. I have finally decided to keep LNA UI-free for now. LNA is already a "heavy" package, I think it's better to spend the remaining ClassPad resources (and my spare time) to implement some more numerical methods than a better way to print matrices.

PD: sorry for my poor English.

Don't worry, my English could be way better as well ;)

*sigh* Yes, that would be nice. Note, however, that making a complete plotting package was never my intention. LNA is mainly a package for numerical computations; plotting capabilities included in LNAplot are for visualizing results obtained by LNA's Numerical Analysis functions. Therefore, I consider logarithmic or semi-logarithmic plots as a low-priority feature.

Then, that for who be interested, I wrote a function to visualize a Matrix in a new window, MatPUI(M,n), the argument M is a Matrix and the argument n is optional and specifies the number of decimals that will have the elements of the Matrix, besides numbers the elements can be string.

Note that you need the MatTrans (LNAUtils) function too.
suggestions and opinions well will be received :)

something more.

PAP, a form exists of plot only a part of the function in a window? for example: plot f(x)=x among 0<x<5 in a window that have some limits among -10<x<10

Nice and certainly useful. I must repeat here that I will keep LNA UI-free for two reasons. First, and most important, I prefer to spend CP resources for more interesting things, like implementing additional numerical methods in LNA. Second, I had several crashes when I tried the UI package, and I don't trust it.

PAP, a form exists of plot only a part of the function in a window? for example: plot f(x)=x among 0<x<5 in a window that have some limits among -10<x<10

No, not currently in LNAplot library, but I can add such a functionality very easily. Thank you for the remark.

Hello,

I need a lua code to find The Maximum and Minimum of a function in a domain .
Do you know any numerical method to do this ?

I have prepared an article about Infinity and some Extended Numerical Methods and their Lua Codes. I will post it here after I have registered the Methods .

Hello ,

Maple Software has two command named Minimize and Maximize and compute the maximum and minimum of a function in a domain even +-Infinity .
but I,m still intersted to have a LNA Library to compute Maximum and Minimum of a function in a domain .

Hi all, and happy new year :)

I admit I am surprised people are still interested on my project. The old good days of the forum seem to be gone, and, in general, very few people replied since I published LNA. That is the main reason I didn't release the latest version, LNA 1.70, despite my plans in the past. Version 1.70 improves latest released version considerably, but it is currently used only by me, since I needed to finish its documentation; this is a lot of work, in order to fulfill LNA's documentation quality standards. I thought there is no reason to bother, since the project was never very popular. However, if I see people are interested, I might release LNA 1.70 as well.

As for hosting LNA in your servers, feel free to do so. It actually makes me happy. Besides, LNA 1.60 was released under the terms of GNU General Public License, so you have the right to distribute LNA as you wish, provided its contents in not modified.

Thank you for your interest on my project. It is always nice for a developer to see his work is useful to other people too. It would be nice if people still using LNA could post what they are doing with it. It will give me the motivation to keep developing the project.

Due to the continuous requests (posts removed to keep the topic clean), here are new links to download LNA. We hope we can keep the links permanent :)

http://www.toppagede...sio/LNA_1.6.zip (Thanks to flyingfisch)

Thank you for this. I suggest to also post a link for LNA's documentation, as it is absolutely necessary to use LNA.

Please keep in mind that LNA 1.7 uses a different (and much more convenient) way to deal with optional arguments. Unfortunately, this means that the syntax is very similar but still incompatible with that of version 1.6. Consequently, if I release version 1.7, all programs based on LNA 1.6 would need minor modifications in order to work with version 1.7.

The documentation PDF is already present there in the zip file. ;)

I think you're going to use table arguments for optional arguments? If you don't change arguments' name and default order then one only has to replace (...) with {...} to make it work, yeah? It shouldn't be so confusing.

I,m still using LNA for my projects . I was so unhappy last years to see that the Cplua and LNA projects were not active .
Your project empower Classpad with new features and it is extending a Language and I use your library as implementation to my programming projects mentioning that this part of code [your library] is copyrighted by you .

I hope you continue developing your project as I was so eager to see version 1.7 in my previous post .
I suggest to Enable Email Notification of replies to be alerted when new comments are added to your project topic .

Nice to see you here again .
and Happy New Year to all users that have this calendar on the Board .

Hi I want to tell you to go ahead with your project, is very good, I recently started programming with lua and extends well the native capabilities of the ClassPad, lua is this similar to the TI Nspire or different?
