DoubleSymPDTriDiagFactSolve(DoubleMatrix) Method

Uses this LDL' factorization to solve the linear system AX = B.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
Syntax
public DoubleMatrix Solve(
	DoubleMatrix B
)

Parameters

B  DoubleMatrix
The matrix of right hand sides. B must have the same number of rows as the factored matrix.

Return Value

DoubleMatrix
A matrix with the same number of columns as B containing the solutions.
Exceptions
ExceptionCondition
SingularMatrixExceptionThrown if the factored matrix is singular.
MismatchedSizeExceptionThrown if the number of rows in B is different than the number of rows in the factored matrix.
Remarks
The ith column of X, X(i), is the solution to the equation AX(i) = B(i), where B(i) is the ith column of B.
