Convert zeros to NAN

I have a matrix (N rows and M columns). It consists of integer values. I want to convert all the zero values from rows 1:N and columns 3:M to NaN. Is there any way to do so.
Thanks, Nancy

One of many ways
idx = ~A;
idx(:,1:2) = false;
A(idx) = nan;

Yes. It sets any value that was a zero value (the ~ (not) command) in the first definition to be false so that it doesn't show up in the nan assignment.
