Function rgsl::linear_algebra::complex_LU_svx

pub fn complex_LU_svx(
    lu: &MatrixComplexF64, 
    p: &Permutation, 
    x: &mut VectorComplexF64
) -> Value

This function solves the square system A x = b in-place using the precomputed LU decomposition of A into (LU,p). On input x should contain the right-hand side b, which is replaced by the solution on output.
