Methods

	Name	Description
	Factor	Factor method for a real positive definite symmetric matrix. (Overrides DoubleSparseFactFactor)
	Factor(SparseMatrixDataCompressedSparseRowT, T)	Factors the input sparse matrix. (Inherited from SparseMatrixFactT)
	SetError	Maps the given MKL integer error code to the appropriate enum value. (Inherited from SparseMatrixFactT)
	Solve(DoubleMatrix)	Uses the current factorization to solve for several right hand sides. (Inherited from DoubleSparseFact)
	Solve(DoubleVector)	Uses the current factorization to solve for the given right hand side. (Inherited from DoubleSparseFact)
	Solve(DoubleVector, DoubleVector)	Uses the current factorization to solve for the given right hand side and places the result in the provided vector. (Inherited from DoubleSparseFact)
