If you have the coefficients (numerical) of a rational function (poles/zeros, etc.) you can use the controls toolbox (ss, zp, tf) to convert from a state space form to transfer function. Alternatively, you can use the impulse function to get the timedomain function corresponding to a strictly proper Laplace domain transfer function.
Thanks for your help. I have a running version of my function at: http://dougs.homeip.net/octave/ilt.m and a test file at http://dougs.homeip.net/octave/ilttest.mI know that for some of us this is trivial but for my students, when they are learning the inverse Lalace transform and partial fraction expansion, I am sure they will use it to check their answers.
Any suggestions and or improvements will be appreciated.
