I have m by n matrix and each element value can be any one of these three number: 0, 48, 49. (I have a code which generates this 3 values).
I want to replace 48 by 0 and 49 by 1. Is there any way to do that?
Thanks.

A - your array with 0,48,49.
[c c c] = unique(A)
d = [0 0 1]
Aout = A;
Aout(:) = d(c)
or
Aout = zeros(size(A));
Aout(A==49) = 1;
