Why did you remove your comment ("n=3; A=magic(n) for i=1:n*n for p=A(i) if rem(p,2)==0 p; end end end i tried this. but could not find the proper answer")?

This sounds a lot like homework. What did you try? I think you will be able to do it yourself if you read the documentation for the mod function.

No double for loop needed. Try this:

n=3;
A=magic(n)
remainders = rem(A, 2) == 0

then use sum() to count the 1's.
