Gaussian filter

Started by enriquefergosa July 11, 2003
Hallo. I am trying to do a gaussian filter using the matlab
function H = FSPECIAL('gaussian',HSIZE,SIGMA). I need to do that the
height of the gaussian is one (that is that the gaussian goes from
zero to one)while the parameter SIGMA is varied to change the wide
of the base. How could I do this? Else, I don't know the
relationship between the parameter SIGMA and the wide of the base.
Somebody could tell me how could I control the wide of the base of
the gaussian to give the value I want in each case?

Thank you all very much.
