WebYou can actually ask the Matlab engine to do anything you can do from within the Matlab interface by calling it from C. A Butterworth filter is recursive, so it should be implemented as an IIR filter. Once you have stable filter coefficients from your Matlab testing you can simply feed them to a generic IIR algorithm (pretty simple).
