% SuiteSparseQR : a multifrontal, multithreaded, rank-revealing sparse QR
% factorization method. Works for both real and complex sparse matrices.
%
% Files
% spqr - multithreaded multifrontal rank-revealing sparse QR.
% spqr_demo - short demo of SuiteSparseQR
% spqr_install - compile and install SuiteSparseQR
% spqr_make - compiles the SuiteSparseQR mexFunctions
% spqr_qmult - computes Q'*X, Q*X, X*Q', or X*Q with Q in Householder form.
% spqr_solve - solves a linear system or least squares problem via QR factorization.
% spqr_singletons - finds the singleton permutation of a sparse matrix A.
%
% Example:
% x = spqr_solve (A,b) ; % solves a least-squares problem (like x=A\b)
