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). + +NOTE: +OpenBLAS can be used instead of blas, and is recommended for better +performance. |
