| Summary | 0000232: IMPLEMENTED: improved complex/real LU decomposition | ||||||
| Description |
Improvements: * new level-3 ALGLIB BLAS is used (future improvements in ALGLIB BLAS will increase LU performance) * cache-oblivious algorithm allows to obtain good performance without tuning for specific CPU * automatic scaling (to avoid overflow when dealing with near-overflow matrices) Other changes: * CLU and LU units are merged, all code moved to TRFAC unit |
