hi;

Any one out there by any chance uses the Mathematica control systems toolbox? V2.02?

I am trying to learn how to use it by implementing Matlab control systems basic problems in Mathematica.

I am getting a problem when I try to obtain the impulse response using a transfer function as the system representation.

I get no such problem when I implement the same example in Matlab.

I was wondering if any one can check this example and who might be using this package who could tell me what is wrong.

I have the complete examples on my web page.

The link to this one specific example is here

It is the example titled

"How to display the response to an impulse of an underdamped, critically damped and over damped system?"

And the complete document with more examples can be found here

I also think the Mathematica documentation for this package could be improved.
