DoubleLUFact Class 
Namespace: CenterSpace.NMath.Core
The DoubleLUFact type exposes the following members.
Name  Description  

DoubleLUFact 
Constructs a DoubleLUFact 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 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.

Name  Description  

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.
 
Factor 
Factors the matrix A so that self represents the LU factorization
of A.
 
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.
