Description

MATLAB sparse matrix converter to Hypre
MATLAB vector converter to Hypre
Hypre sparse matrix converter to MATLAB
Hypre vector converter to MATLAB

The Parallel High Performance Preconditioners (hypre) is a library of routines for scalable (parallel) solution of linear systems. The built-in BLOPEX package in addition allows solving eigenvalue problems. See http://en.wikipedia.org/wiki/Hypre and http://en.wikipedia.org/wiki/BLOPEX

Hypre currently does not have a direct MATLAB interface. These codes allow one to transfer data between hypre and MATLAB/OCTAVE.

Our previous code,
http://www.mathworks.com/matlabcentral/fileexchange/7421-matlab-to-hypre-and-hypre-to-matlab-matrix-and-vector-converter
is not Hypre 2.6.0b compatible.

GNU OCTAVE compatible. Tested with Octave 3.2.3 and Hypre 2.6.0b.

This code is a part of the BLOPEX package:

Hypre does NOT support complex arithmetic. A complex valued matrix in MATLAB will be transformed into a real matrix by the matlab2hypre code, by simply dropping the imaginary part. No warning is generated by the code in this case.
