Functions

void clsolve (int ldm, int ncol, complex *M, complex *rhs)
 Solves a dense UNIT lower triangular system.
void cusolve (int ldm, int ncol, complex *M, complex *rhs)
 Solves a dense upper triangular system.
void cmatvec (int ldm, int nrow, int ncol, complex *M, complex *vec, complex *Mxvec)
 Performs a dense matrix-vector multiply: Mxvec = Mxvec + M * vec.


Detailed Description

 -- SuperLU routine (version 2.0) --
 Univ. of California Berkeley, Xerox Palo Alto Research Center,
 and Lawrence Berkeley National Lab.
 November 15, 1997
 
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 clsolve int  ldm,
int  ncol,
complex M,
complex 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 cmatvec int  ldm,
int  nrow,
int  ncol,
complex M,
complex vec,
complex Mxvec
 

The input matrix is M(1:nrow,1:ncol); The product is returned in Mxvec[].

void cusolve int  ldm,
int  ncol,
complex M,
complex 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.
