Detailed Description

SparseQR solver.

From the README file:
This routine computes the QR decomposition of a mxn matrix A, m>=n, such that

$P_r \cdot Q^\top \cdot A \cdot P_c^\top = \begin{pmatrix} R \\ 0 \end{pmatrix}$

where $Q^\top \cdot Q = I \in R^{m\times m}$ , $R \in R^{m\times m}$ is an upper triangular mxm matrix and $P_r\in R^{m\times m}$ as well as $P_c\in R^{n\times n}$ are permutation matrices.
