"The Sparse QR routines provide a multifrontal sparse QR factorization method for solving a sparse system of linear equations.' I am using PARDISO to solve a sparse linear of equations, and at least it is what I understand PARDISO is for. Even if the 2 functions can do other things, at...
Both qr's are "correct" in that sense (a1*r1 == a2*r2). a2 is an identity (except for the last 3 columns which are 0). r2 matches the "q-less" qr (from dgeqrf.f), r1 doesn't. In a perfect world, I would like the r's from the q-less sparse and non-sparse qr to ...
Solved: Hello, I am experimenting the Sparse QR library to solve a linear system of equations. When I run the attached file, I get the following

Python wrapper for SuiteSparseQR This module wraps theSuiteSparseQRdecomposition function for use withSciPy. This is Matlab's sparse[Q,R,E] = qr(). For some reason, no one ever wrapped that function of SuiteSparseQR for Python. Also wrapped are the SuiteSparseQR solvers forA x = bfor the...
Third, call the factorization step of Sparse QR. Herealt_values(a double precision array) can be added in order to perform the factorization with a matrix, which values are different from the initial matrixAbut that has the same sparsity pattern. IfNULLvecto...
