﻿DoubleLUFact Members

The DoubleLUFact type exposes the following members.

# Constructors

NameDescription
DoubleLUFact
Constructs a DoubleLUFact instance by factoring the given matrix.

# Methods

NameDescription
Clone
Creates a deep copy of this factorization.
ConditionNumber
Computes the reciprocal of the condition number of a given matrix in the specified norm type.
Determinant
Computes the determinant of the factored matrix.
Equals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Factor
Factors the matrix A so that self represents the LU factorization of A.
GetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
GetType
Gets the type of the current instance.
(Inherited from Object.)
Inverse
Computes the inverse of the factored matrix.
Solve(DoubleMatrix)
Uses this LU factorization to solve the linear system AX = B.
Solve(DoubleVector)
Uses the LU factorization of self to solve the linear system Ax = b.
SolveInPlace(DoubleMatrix)
Uses this LU factorization to solve the linear system AX = B.
SolveInPlace(DoubleVector)
Uses the LU factorization of self to solve the linear system Ax = b.
ToString
Returns a string that represents the current object.
(Inherited from Object.)

# 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 eqations, compute determinants, inverses, and so on; otherwise false.
IsSingular
Gets a boolean value which is true if the matrix factored is singular; otherwise, false.
L
Gets the lower triangular matrix L from the factorization PA = LU, where A is the matrix that was factored.
P
Gets the permutation matrix P from the factorization PA = LU, where A is the matrix that was factored.
Pivots
Gets an array of pivot indices. The row i was interchanged with row Pivots[i].
Rows
Gets the number of rows in the matrix represented by the factorization.
U
Gets the upper triangular matrix U from the factorization PA = LU, where A is the matrix that was factored.
