A non-GUI function that will smooth a time series using a simple Gaussian filter.
Usage:
zfilt = gaussfilt(t,z,sigma);
where t & z define the time series (t independent variable and z is data vector), and sigma defines the standard deviation (width) of the Gaussian filter.
jon, thanks for the feedback. I originally wrote the function for a non-uniformly spaced time vector, which conv would not handle correctly. That said, I expect most uses of this function will be for uniformly spaced time vectors, where your criticism is exactly right.
I uploaded an update that will look to do the convolution unless the spacing is variable, in which case it will use the (ugly) loop.
