The DoubleSymFact type exposes the following members.

Constructors

	Name	Description
	DoubleSymFact(DoubleSymmetricMatrix)	Constructs a DoubleSymFact instance by factoring the given matrix. By default the condition number for the matrix will not be computed and will not be available from the ConditionNumber method.
	DoubleSymFact(DoubleSymmetricMatrix, Boolean)	Constructs a DoubleSymFact instance by factoring the given matrix.

Properties

	Name	Description
	Cols	Gets the number of columns in the matrix represented by the factorization.
	IsGood	Gets a boolean value which is true if the matrix factorization succeeded and the factorization may be used to solve equations, compute determinants, inverses, and so on; otherwise false.
	IsSingular	Gets a boolean value which is true if the matrix is Singular and the factorization may NOT be used to solve equations, compute determinants, inverses, and so on; otherwise true.
	Rows	Gets the number of rows in the matrix represented by the factorization.

Methods

	Name	Description
	Clone	Creates a deep copy of this factorization.
	ConditionNumber	Computes an estimate of the reciprocal of the condition number of a given matrix in the 1-norm.
	Determinant	Computes the determinant of the factored matrix.
	Factor(DoubleSymmetricMatrix)	Factors the matrix A so that self represents the factorization of A. By default the condition number for the matrix will not be computed and will not be available from the ConditionNumber method.
	Factor(DoubleSymmetricMatrix, Boolean)	Factors the matrix A so that self represents the factorization of A.
	Inverse	Computes the inverse of the factored matrix.
	Solve(DoubleMatrix)	Uses this factorization to solve the linear system AX = B.
	Solve(DoubleVector)	Uses the factorization of self to solve the linear system Ax = b.
