hi,
try testing your own ideas, as a first test try to set a function
Y= Gaussian_Filter(X,sigma)
% So you have input signal X and standard deviation sigma
% ADD your own code here : is it convolution, simple multiplication,....
%set Gaussian kernel
%constant=....
kernel = exp(-constant/2*(sigma^2));
%Y=conv(X,kernel) as example

Since this is standard functionality, you can expect that someone has already implemented this and shared this in File Exchange:
You can take a look at them to implement you own or use them yourself.
