I have an easy question;

I have a matrix ( x row, x columns) filled with 0s and 1s.

I want to check if there is a 1 in every row (for every column).

then result that in a new matrix

so basically it is this

0 0 0 = 0 1 0 0 = 1 0 1 0 = 1 0 0 1 = 1

What should happen for [1,1,0] and [1,1,1]?

Not that it matters, but you don't have x rows and x columns - your matrix is not square. Plus your answer does not check for a 1 in

everyrow foreverycolumn. That would be an array that iscompletely all 1's. You don't even check for 1's in every column. You're just checking each row if there isa1, which is quite different. Plus we don't even know if you need exactly one 1, or if multiple 1's should also produce a 1 for that row in your output vector.## Hello kity (view profile)

I can only get a single 1 at each row, that is how my data is buildup.
