hey,
I'm trying to use MATLAB to simulate a simple RC low pass filter. I have an array of data that represents the signal I want to filter, and I have the s-domain representation of the filter circuit. I'm pretty new to this type of analysis, but I'm pretty sure I should be taking the fft...
dunno if anyone is still looking at this thread but I found this site really helpful

the gradient and cumtrapz functions took care of it.
