- TODO
- Date_ 2009-10-03
- * Add ATLAS wrapper for blas level 2 and level 3 functions.
- * Include the HAVE_ATLAS definition in the configure system
- * Replace the lu-solver in lu.c with the one from the ccmath library
- and patch all modules using lu.c
- * Implement a robust parallelizable LU solver with pivoting
- * Move the band matrix cholesky decomposition solver from the lidar library
- (TcholBand.c) into the gmath library and make it available for other numerical
- programs (Integration in the common solver structure)
