My matrix is Y=[1 2 5 0; 3 4 0 0; 7 0 3 0; 0 0 0 1]
I want to replace zeros '0' with '0.001'
How can I do it basically?
Thanks a lot!

As long as 0 is exactly 0 (and not some very small value that's close to zero):
Y(Y==0) = 0.001;
Probably better would be, if all Y>=0
Y(Y<0.001) = 0.001;

I don't understand what you're asking now. My answer will work whatever the shape and number of dimensions of Y.
