If not, lets suppose I have the matrix in row echelon, N. So I create an empty list. Basically, I want to say while i< # of rows, if row i of row echelon form matrix N has a 1, put M[i] in list. But I don't know how to say if a row has a 1( a pivot).
P.s., yes I need the rows. My matrix is like transposed.whatupmattMon, 01 Jun 2020 00:52:22 +0200https://ask.sagemath.org/question/51662/
