MATLAB symbolic to numeric
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 of my data and multiplying it by the s-domain representation (transfer function) of the circuit, and then take the ifft to get the output.
I guess my problem is I have a symbolic transfer function that I'm trying to multiply with a numeric array. Any Ideas on how I can get a numeric representation of my symbolic transfer function?
Thanks in advance.
(this is my transfer function if that helps)
transferFunc = 100/(s+100)

You probably want something called a Bode plot (magnitude and phase angle of a Linear Time Invariant system):
If you have the MATLAB Controls Toolbox, you can generate a Bode plot of a system given its transfer function:

Thanks a million MATLABdude,
That tutorial held all the answers and more! :)
