Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public static FloatMatrix SolvePD(
	FloatSymCsrSparseMatrix A,
	FloatMatrix B
)

Public Shared Function SolvePD ( 
	A As FloatSymCsrSparseMatrix,
	B As FloatMatrix
) As FloatMatrix

public:
static FloatMatrix^ SolvePD(
	FloatSymCsrSparseMatrix^ A, 
	FloatMatrix^ B
)

static member SolvePD : 
        A : FloatSymCsrSparseMatrix * 
        B : FloatMatrix -> FloatMatrix

A FloatSymCsrSparseMatrix: A CSR Symmetric Positive Definite Sparse matrix.
B FloatMatrix: The matrix of right hand sides. B must have the same number of rows as A.

FloatMatrix
A matrix with the same number of columns as B containing the solutions.

Exceptions

Exception	Condition
MismatchedSizeException	Thrown if the number of rows in B is different than the number of rows in A.
NMathException	Thrown if there is an error solving the system or if A is not positive definite.

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.
