Resize Matrix Rows and Cols in Matlab

Question

I have imported data in MATLAB as a matrix called A with a size

48 x 52 (48 Rows X 52 Columns).

How do I RESIZE the matrix to 48 X 48 in Matlab?

Answer 1

If you don't care about losing whatever data is in those columns, you can delete the last 4 columns using

A(:,49:52) = []

Otherwise, I'd assign to a new matrix as HPM suggested.

Answer 2

Well

B = A(:,1:48)

will make B a 48x48 matrix which matches part of A. Is that what you want ?
