This function returns coefficients of Gaussian ...

This function returns coefficients of Gaussian lowpass filter.
Advantages of gaussian filter: no ringing or overshoot in time domain.
Diasadvantage: slow rolloff in frequency domain.
Pass SR=sampling rate, fco=cutoff freq, both in Hz, to the function.
Coefficients for FIR filter of length L (L always odd) are computed.
This symmetric FIR filter of length L=2N 1 has delay N/SR seconds.
Examples of use:
Compute Gaussian filter frequency response when SR=1000, fco=50 Hz:
freqz(gaussfiltcoef(1000, 50), 1, 256, 1000);
Filter signal X sampled at 5kHz with Gaussian filter with fco=500:
y=filter(gaussfiltcoef(5000, 500), 1, X);
SR, fco are not sanity-checked. WCR 2006-10-11.
