I have placed a program in the area of shared files called: LAC002:three automatic control functions.

It contains the RootP to find all roots of a polynomial, a function previously sent, and two new functions:
Residue to perform the partial fraction expansion of a quotient of two polynomials
and StepUnit: to obtain the unit step temporal response of a linear system: graphically and numeric.

This functions are comented and ilustrated with examples. The examples are in the folder: LACexam. In addition there are two auxiliary functions: Series and FBack (feedback) described.

Thanks.

I am also working on a similar subject. The next feature that I want to implement is the bode diagram.
I was carrying a lot of work because I have to write the program for drawing graphs. I need to have two separate graphics (for gain and phase) on the same screen in semilogar?tmic scale and the graph functions of PAP on LNA would not permit.Posted Image

What kind of functions are you writing in your toolbox?. If you need some help or want to intechange information don't hesitate to write me.Posted Image

Multiple and/or animated plots are already implemented in LNA 1.70, but that version is not released yet, due to the lack of time (documentation is not finished yet). But if you need such features urgently, I can release a "not completely documented version" ;)

Your programs are welcome because they are very useful. But the program I'm developing I started with the graphical interface and it is already finished. Thanks for your (in advance) offering.Posted Image
