WebSep 20, 2016 · If A is a square matrix, there is a unique solution if and only if det ( A) ≠ 0. Putting these tests together we have for all square matrices A, A x = b has. no solution if b is not in the column space of A. a unique solution if det ( A) ≠ 0. infinitely many solutions if b is in the column space of A but det ( A) = 0. WebFeb 21, 2024 · So far I managed to write the code required to find the matrices P,L,U given matrix A, but I ran into trouble when it came time to compute the determinant. Since the PA = LU method uses pivoting, the determinant should be the same as the A = LU method, but might be of different sign depending on how many pivoting has been performed.
