Hello!
I have matrix S that contains zeros and ones. and I want to convert it to a column vector contianing one in the ith position if there was at least one one in the ith row.
So I know that "or" operation does similar job but with two vectors. is there a way to use it with the columns of S ?

Try
rowHasOnes = any(S, 2);
If not, then supply an example S and the expected result.
