As I said, I'm trying to speed up the operation of a simple IIR filter. That's it.
I was wondering if someone has any experience with that. Is it possible to beat Matlab's "filter" command with a MEX file? Anyone has ever managed to beat the filter command using other Matlab's built in functions?
The functionality I need is to define an IIR filter and apply it a Matrix of data. I want to do it as fast as possible.
