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

pub fn QRPT_QRsolve(q: &MatrixF64, r: &MatrixF64, p: &Permutation, b: &VectorF64, x: &VectorF64) -> Value

This function solves the square system R P^T x = Q^T b for x. It can be used when the QR decomposition of a matrix is available in unpacked form as (Q, R).
