Functions
void	mPlaceit (int *IA, int *JA, double *A, int key, int i, int j, double val)
	Set or add a value to a matrix row/column.
void	mContrib (Vset *mtpool, int key, int *count, int i, int j, double val)
	Set or add a value to a linked matrix entry list.
void	lContrib (Vset *mtpool, int *count, int i, int j)
	Add a link to a linked graph entry list.
void	mBuildGraphT (Vmem *vmem, int **IJAT, double **AT, int *ATnumO, int *IJA, double *A, int n, int m, int flag, int *work)
	Builds an index (and value) array in transposed format given the index and value array of a ROW or COL matrix.
void	buildG (Vmem *vmem, MATformat frmt, MATsym sym, int m, int n, int *numO, int *numA, int **ijb, double **b, int **ib, int **jb, double **diagb, double **offUb, double **offLb, int *ir, int *jr, double *r, int *ia, int *ja, double *a, double *diag, double *offU, double *offL, int *ip, int *jp, double *p)
	Produce the sparse triple matrix product: B = R*A*P, where A is a sparse NxN square matrix, R is a sparse MxN retangular matrix, and P is a sparse NxM rectangular matrix, with M < N (possibly M << N). The result is a smaller (but possibly much more dense) square MxM matrix B.
