The FloatSymPDTriDiagFact type exposes the following members.
Name | Description | |
---|---|---|
FloatSymPDTriDiagFact(FloatTriDiagMatrix) | Constructs a FloatSymPDTriDiagFact 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. | |
FloatSymPDTriDiagFact(FloatTriDiagMatrix, Boolean) | Constructs an FloatSymPDTriDiagFact instance by factoring the given matrix, optionally estimating the condition number of the 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. | |
IsPositiveDefinite | Gets a boolean value which is true if the matrix is positive definite and the factorization may be used to solve equations, compute determinants, inverses, and so on; otherwise false. | |
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(FloatTriDiagMatrix) | Factors the matrix A so that self represents the LDL' 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(FloatTriDiagMatrix, Boolean) | Factors the matrix A so that self represents the LDL' factorization of A. By default the condition number for the matrix will not be computed and will not be available from the ConditionNumber method. | |
Inverse | Computes the inverse of the factored matrix. | |
Solve(FloatMatrix) | Uses this LDL' factorization to solve the linear system AX = B. | |
Solve(FloatVector) | Uses the LDL' factorization of self to solve the linear system Ax = b. |
A = LDL'
