Here's how to remove rows or columns that contain only 0s
data = [0 0 0 0; 0 4 5 2; 0 2 5 4; 0 2 4 1]
data = 4×4
0 0 0 0 0 4 5 2 0 2 5 4 0 2 4 1
rowsAll0 = all(data==0,1); % columns of 0s
data(:, rowsAll0) = [];
colsAll0 = all(data==0,2); % rows of 0s
data(colsAll0, :) = []
data = 3×3
4 5 2 2 5 4 2 4 1
