int DSDPSchurMatDiagonalScaling	(	DSDPSchurMat	M,
		DSDPVec	D
	)

Get the scaling and nonzero pattern of each diagonal element of the matrix.

Parameters:

	M	matrix
	D	multply each element of the diagonal by this quantity.

Conic object call this routine when evaluating the Hessian of the barrier term. The elements will be a 0 or a 1. Important for parallel version.

int DSDPSchurMatRowColumnScaling	(	DSDPSchurMat	M,
		int	row,
		DSDPVec	V,
		int *	nzcols
	)

Get the scaling and nonzero pattern of each column in this row of the matrix.

Parameters:

	M	matrix
	row	correponding to variable y
	V	multply each element of the row by this quantity.
	nzcols	how many nonzeros. Check for a 0! Conic object call this routine when evaluating the Hessian of the barrier term. The vector V identifies sparsity, whether its using upper or lower half of Schur, and also used to distribute rows over processros The elements will be a 0 or a 1. This routine is to be used with DSDPSchurMatAddRow().
