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

DoubleSymPDBandFact(DoubleSymBandMatrix) 
Constructs a DoubleSymPDBandFact 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.
 
DoubleSymPDBandFact(DoubleSymBandMatrix, Boolean) 
Constructs an DoubleSymPDBandFact 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.
 
HalfBandwidth 
Gets the half bandwidth of the factored symmetric banded matrix.
 
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
factored is positive definite; 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
with respect to the one norm.
 
Determinant 
Computes the determinant of the factored matrix.
 
Factor(DoubleSymBandMatrix) 
Factors the matrix A so that self represents the LU 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(DoubleSymBandMatrix, Boolean) 
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 factorization to solve the linear system AX = B.
 
Solve(DoubleVector) 
Uses the LU factorization of self to solve the linear system Ax = b.
