Double |
The DoubleSymFact type exposes the following members.
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. |
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. |
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. |
