Good day,
Please how can I replace all elements of a row with zeros if any of the elements in the row is greater than 1.
For instance; I have a 4X3 Matrix;
A= [0.2 0.5 0.1
0.4 0.6 3.0
0.2 0.5 0.1
2.0 0.5 0.1]
Only raw 2 and row 4 contain element that is greater than 1.
so the output will be = [0.2 0.5 0.1
0.0 0.0 0.0
0.2 0.5 0.1
0.0 0.0 0.0]
Thanks in anticipation of your help

Another method if you want the replacement in-place:
A(any(A>1,2),:) = 0;

Exactly as I want it

out = all(A <= 1,2).*A

But when I run it, I got exactly the same matrix as A.
The response by James below solved my problem.
thanks
