Function Documentation

FUNCTION void sse_iovect_callback	(	const long *	n,
		const long *	m,
		double *	q,
		const long *	j,
		const long *	k
	)

Callback for saving the Lanczos vectors as required by dnlaso.

If k=0, save the m columns of q as the (j-m+1)th through jth vectors. If k=1 then return the (j-m+1)th through jth vectors in q.

FUNCTION void sse_op_callback	(	const long *	n,
		const long *	m,
		const double *	p,
		double *	q
	)

Callback for multiplying our matrix by a number of vectors.

The input is p, which is an NxM matrix. This function returns q = A p, where A is the current sparse matrix.
