pub fn lapack_dgetrf(a: &Matrix) -> Result<LuFactors>Expand description
LU factorization with partial pivoting of a general m × n matrix,
A = P L U (igraph_lapack_dgetrf), where L is lower triangular
(trapezoidal if m > n) with unit diagonal and U is upper triangular
(trapezoidal if m < n).
A singular matrix is not an error: check LuFactors::info.
