| void | dlsolve (int ldm, int ncol, double *M, double *rhs) |
| Solves a dense UNIT lower triangular system. | |
| void | dusolve (int ldm, int ncol, double *M, double *rhs) |
| Solves a dense upper triangular system. | |
| void | dmatvec (int ldm, int nrow, int ncol, double *M, double *vec, double *Mxvec) |
| Performs a dense matrix-vector multiply: Mxvec = Mxvec + M * vec. | |
-- SuperLU routine (version 2.0) -- Univ. of California Berkeley, Xerox Palo Alto Research Center, and Lawrence Berkeley National Lab. November 15, 1997Purpose: Level 2 BLAS operations: solves and matvec, written in C. Note: This is only used when the system lacks an efficient BLAS library.
| void dlsolve | ( | int | ldm, | |
| int | ncol, | |||
| double * | M, | |||
| double * | rhs | |||
| ) |
The unit lower triangular matrix is stored in a 2D array M(1:nrow,1:ncol). The solution will be returned in the rhs vector.
| void dmatvec | ( | int | ldm, | |
| int | nrow, | |||
| int | ncol, | |||
| double * | M, | |||
| double * | vec, | |||
| double * | Mxvec | |||
| ) |
The input matrix is M(1:nrow,1:ncol); The product is returned in Mxvec[].
| void dusolve | ( | int | ldm, | |
| int | ncol, | |||
| double * | M, | |||
| double * | rhs | |||
| ) |
The upper triangular matrix is stored in a 2-dim array M(1:ldm,1:ncol). The solution will be returned in the rhs vector.
