Function Documentation

zlsolve()

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.

Here is the caller graph for this function:

zmatvec()

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[].

Here is the caller graph for this function:

zusolve()

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.
