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
