Function rgsl::linear_algebra::QR_solve

pub fn QR_solve(qr: &MatrixF64, tau: &VectorF64, b: &VectorF64, x: &VectorF64) -> Value

This function solves the square system A x = b using the QR decomposition of A held in (QR, tau) which must have been computed previously with gsl_linalg_QR_decomp. The least-squares solution for rectangular systems can be found using QR_lssolve.
