Function Documentation

DSDPSchurMatOpsInitialize()

int DSDPSchurMatOpsInitialize

(

struct DSDPSchurMat_Ops *

dops

)

Initialize function pointers to 0.

Parameters

dops	address of a structure of function pointers.

DSDPSetSchurMatOps()

int DSDPSetSchurMatOps	(	DSDP	dsdp,
		struct DSDPSchurMat_Ops *	sops,
		void *	mdata
	)

Set the Schur complement matrix.

Parameters

dsdp	the solver
sops	address of a structure with function pointers
mdata	address of a matrix object

The step direction in DSDP is the solution to a set of linear equations. The cones used by DSDP compute the elements of the matrix and the right-hand side vectors. Any matrix that implements the Schur complement matrix interface can be used by DSDP. In addition to factoring a matrix and solving it, this interface also provides matrix assembly routines for the cones.
