By the same OP (the accepted solution uses padarray):

Answer 1

[Jos (10584)]

A = magic(4)
n = 2
B = padarray(A,[n n]) % pad
A2 = B(n+1:end-n,n+1:end-n) % unpad

or directly:

A2 = A

Simply don't call it. Why did you call it if you don't want what it does?

Like Jos says, you can just extract the central part with indexing:

out = yourArray(2:end-1, 2:end-1);
