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.

SuperLU contains a set of subroutines to solve a sparse linear system
|
|
A*X=B. It uses Gaussian elimination with partial pivoting (GEPP).
|
|
The columns of A may be preordered before factorization; the
|
|
preordering for sparsity is completely separate from the factorization.
|
|
|
|
SuperLU is implemented in ANSI C, and must be compiled with standard
|
|
ANSI C compilers. It provides functionality for both real and complex
|
|
matrices, in both single and double precision. The file names for the
|
|
single-precision real version start with letter "s" (such as sgstrf.c);
|
|
the file names for the double-precision real version start with letter "d"
|
|
(such as dgstrf.c); the file names for the single-precision complex
|
|
version start with letter "c" (such as cgstrf.c); the file names
|
|
for the double-precision complex version start with letter "z"
|
|
(such as zgstrf.c).
|
|
|
|
SuperLU was modified for Blender to only include single-precision
|
|
functionality.
