Function rgsl::linear_algebra::QRPT_svx [−] [src]

pub fn QRPT_svx(qr: &MatrixF64, tau: &VectorF64, p: &Permutation, x: &VectorF64) -> Value

This function solves the square system A x = b in-place using the QRP^T decomposition of A held in (QR,tau,p). On input x should contain the right-hand side b, which is replaced by the solution on output.
