Hi guys, I have a question. I have an 8 by 8 matrix for instance, and I tried to shrink it into 5 by 5 matrix. Does the Matlab have the way to do that? I try to extract the odd element in rows and columns but it cannot the exact size of the matrix I want. For example Y = I(1:2: end,1:2: end) and in 8 by 8 matrix case, it will only output the 4 by 4 matrix. Thank you
