Syntax

The FloatHermitianFact type exposes the following members.

Constructors

Name | Description | |
---|---|---|

FloatHermitianFact(FloatHermitianMatrix) | Constructs a FloatHermitianFact 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. | |

FloatHermitianFact(FloatHermitianMatrix, Boolean) | Constructs a FloatHermitianFact 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. |

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(FloatHermitianMatrix) | 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(FloatHermitianMatrix, Boolean) | Factors the matrix A so that self represents the factorization of A. | |

Inverse | Computes the inverse of the factored matrix. | |

Solve(FloatComplexMatrix) | Uses this factorization to solve the linear system AX = B. | |

Solve(FloatComplexVector) | Uses the factorization of self to solve the linear system Ax = b. |
