gausssmooth filter

[pietropicerno]

Hi Jens,
is there any particular reason why you don't let the user to input a sigma value <1 in the editor? Somewhere else in this forum I asked for a Butterworth filter and I might find something similar to it: I read that the Gaussian filter is basically a low-pass filter (what I'm looking for) where the cutoff frequency can be controlled by setting the sigma value so that:

Code:

Fc = 1/(2*pi*sigma)

Here's the source: https://stackoverflow.com/questions/4447...-frequency

A 3.5 Hz (the cutoff I'd like to use) would then require a sigma value less than 1....that's why I'm asking.
Let me know.
Thanks,
Pietro
