MATLAB: From a matrix, Pick one element from each row and not from same column for all possibilities. Only for non zero elements.

Question

Hi, From a matrix, I would like to pick one element from each row and not from same column for all possibilities.

Only for non zero elements.

Example, from A = [1 2 0; 1 2 0; 0 0 3], I want to obtain (1 2 3 and 2 1 3).

Thank you

Hi,

Your requirements are answered in a similar question mentioned in this link. Also, selecting set of elements from a matrix such that each element comes from distinct row and column can also be modeled as a Matching problem. (graph theory)
