Detailed Description

-- SuperLU routine (version 2.0) --
Univ. of California Berkeley, Xerox Palo Alto Research Center,

Purpose: Level 2 BLAS operations: solves and matvec, written in C. Note: This is only used when the system lacks an efficient BLAS library.

Function Documentation

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.
