Function Documentation

void dlsolve	(	int	ldm,
		int	ncol,
		double *	M,
		double *	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:

void dmatvec	(	int	ldm,
		int	nrow,
		int	ncol,
		double *	M,
		double *	vec,
		double *	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:

void dusolve	(	int	ldm,
		int	ncol,
		double *	M,
		double *	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.

Here is the caller graph for this function:
