Added SuperLU 3.0: http://crd.lbl.gov/~xiaoye/SuperLU/ This is a library to solve sparse matrix systems (type A*x=B). It is able to solve large systems very FAST. Only the necessary parts of the library are included to limit file size and compilation time. This means the example files, fortran interface, test files, matlab interface, cblas library, complex number part and build system have been left out. All (gcc) warnings have been fixed too. This library will be used for LSCM UV unwrapping. With this library, LSCM unwrapping can be calculated in a split second, making the unwrapping proces much more interactive. Added OpenNL (Open Numerical Libary): http://www.loria.fr/~levy/OpenNL/ OpenNL is a library to easily construct and solve sparse linear systems. We use a stripped down version, as an interface to SuperLU. This library was kindly given to use by Bruno Levy.

This is OpenNL, a library to easily construct and solve sparse linear systems.
* OpenNL is supplied with a set of iterative solvers (Conjugate gradient,
BICGSTAB, GMRes) and preconditioners (Jacobi, SSOR).
* OpenNL can also use other solvers (SuperLU 3.0 supported as an OpenNL
extension)
Note that to be compatible with OpenNL, SuperLU 3.0 needs to be compiled with
the following flag (see make.inc in SuperLU3.0):
CDEFS = -DAdd_ (the default is -DAdd__, just remove the second underscore)
OpenNL was modified for Blender to be used only as a wrapper for SuperLU.
