Thanks JoeI did look there and there is nothing for Inverse Laplace transform that I can see.
I have written up a crude version that is not ready for prime time yet. I thought I would ask before I spent the time to reinvent the wheel :)
What I have is a function ( for the controls tool box) that takes in a sys type transfer function. It then uses the residue function to do the partial fraction expansion.From this I form up a string that is the time representation of each factor. What I am having a little difficulty with is how to get the string formatted nicely.
I have a cell array with each location holding a string that is the time representation of a term. What I want to do is take these and form them into one long string that has all the "+"'s and ""'s between each term properly formated.
So any help would be appreciated. resultstring = cell(1,1) "+" cell(2,1) "" cell(3,1) is what I can't seem to do? Thanks in advance for any help. Doug Stewart
