Hi, I have this question:
I have a matrix whose pixel value represent a gaussian beam. For my experimental purpose I want to make it smaller in a matrix of equal dimensions and I have decided to do this:
Q=padarray(A, [1000*t 1000*t], 0);
SS=imresize(Q,[1000 1000]);
I encrease the matrix dimension then I resize it at the original dimension. Now what I am expecting is to see a smaller gaussian profile. But I see this:
The first matrix is the original one, the second one is the resized one. Why we dont see a gaussian.

Still more undefined vars.
Unrecognized function or variable 'gran'.
Error in ProvaSito (line 17)
for k=1:gran:(size2-gran)
Perhaps you could download your attachment and try to run it after clearning your workspace. Then you can find the missing vars and supply them.
