Hello everyone!
i have a binary matrix R(m*n), each row has multiple "1" , i want to optimize it in order to get only "1" in each row and no more than 3 "1" in each column. i want to user an optmizer but all of them need an optmization function. so can i return the matrix to a function in order to solve this problem?
thanks in advance

What kind of problem ?
As I said, there are of course matrices for which no solution exists. And the smaller you choose the possible number of ones per column, the greater the probability.
But if the solver says that a feasible solution can not be found, you can trust that your matrix doesn't permit a solution.

Yes, you can return a matrix from the function. However, that would be considered multiple objectives, and you would need to use one of the multi-objective optimizers.
To use optimizers such as fmincon() or ga() your objective function needs to return a scalar (well, except as determined by any UseVectorized option that might be in effect.)
... which I already told you in your earlier question.
