Function Documentation

void zlsolve ( int  ldm,
int  ncol,
doublecomplex M,
doublecomplex rhs 
)

 Solves a dense UNIT lower triangular system. 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 zmatvec ( int  ldm,
int  nrow,
int  ncol,
doublecomplex M,
doublecomplex vec,
doublecomplex Mxvec 
)

 Performs a dense matrix-vector multiply: Mxvec = Mxvec + M * vec.
 The input matrix is M(1:nrow,1:ncol); The product is returned in Mxvec[].
 

void zusolve ( int  ldm,
int  ncol,
doublecomplex M,
doublecomplex rhs 
)

 Solves a dense upper triangular system. 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.
