The DoubleSymFact type exposes the following members. Constructors
NameDescription 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.
Top Properties
NameDescription 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.
Top Methods
NameDescription 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.
