MATLAB has a built in function butter in the Signal Processing Toolbox that will return coefficients for a Butterworth high- or lowpass filter. Type help butter in the command window. Once you have coefficients, use filter ("standard" filtering) or filtfilt (zero-phase) to perform the filtering.

The solution is correct. I do no think, that GITS will still need this after 10 months, but for other readers it can be useful.
