Delete non-zero rows in MATLAB

Question

I have used the following code in MATLAB to delete the zero rows,

zero_rows = A(all(A,2),:);

I would like to know how to delete the non-zero rows.

Answer 1

Just use the not sign ~ or use any

non_zero_rows = A(~all(A,2),:);

or

zero_rows = A(any(A,2),:);
