Function Documentation

void zlsolve	(	int	ldm,
		int	ncol,
		doublecomplex *	M,
		doublecomplex *	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 zmatvec	(	int	ldm,
		int	nrow,
		int	ncol,
		doublecomplex *	M,
		doublecomplex *	vec,
		doublecomplex *	Mxvec
	)

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
	)

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.
