i recently write a program to plot Bode Diagram for fx-9860g

features:
1-plot magnitude and phase
2-semi logarithmic plot
3-Generate logarithmically spaced frequency with log space function(like logspace.m in MATLAB)
4-Correct phase angles to produce smoother phase plots with unwrap function(like unwrap.m in MATLAB)
5-plot system that have Dead Time(e^(-s))

PREVIEW

see below link that plot a system with MATLAB and ti 89:
http://csserver.evan...bode_plots.html

i plot that system with my casio-fx 9860g(it completely look like MATLAB plot):

transfer function

Magnitude Plot from a casio fx-9860g

Phase Plot from a casio fx-9860g

Magnitude Plot from a TI-89

Phase Plot from a TI-89

Bode Plot from Octave/MATLAB (freq. in rad/s)

I test this program like a user because nobody want to help me for try this program

never mind
i correct some bugs of this program and i can not find anything else
in this version you can turn Grid On or Off

i now working on the help document

[amin_heidari]

it now accessible in File Sharing

i'm going to work on the Nyquist Plot for fx-9860g

[amin_heidari]

Nyquist Plot is accessible in File Sharing

i write program for plot nichols diagram too

it will accessible in the Next Week

[flyingfisch]

Nice program!

[ECE]

Hi,
Very interesting, I’ll try to examine the program with systems like non-minimum phase and non-causal systems.
Regards

[amin_heidari]

nichols diagram will be ready soon
features:
1- support nichols chart for plot grid
2- unwrap phase
3- log space function

Open-Loop Transfer Function

i will update Bode Diagram Program for:
Compute Gain and Phase margins and associated crossover frequencies

i'm suspense to add new function named MARGIN to BODE.G1M or write new program(stand alone) to produce above value(Gm,Pm,Wcg,Wcp) !!!???

what you say?

[amin_heidari]

i update Root Locus(V0.4) program
new features:
1- it use new version of Str2Poly(V0.55) function that can expand
equation
2- it use Line Space function to generates equally
spaced point
3- it 1.3X faster than previous version
4- it work completely look like MATLAB function(rlocus.m)

[amin_heidari]

i update Root Locus(V0.5) program again
new features:
1- automatic scaling added
2- wait bar added

[flyingfisch]

Mind if I port this to prizm sometime?

[amin_heidari]

Mind if I port this to prizm sometime?

what ?

[flyingfisch]

The program

[amin_heidari]

Yeh why not :-)

[flyingfisch]

Cool thx

[Michaeltharwat_]

PLEASE, i'm a new user for the calculator and i wanna use your program but i can't reach the source to download it so please help me
