) As Preconditioner(Of T)

public:
Preconditioner<T>^ CreatePreconditioner(

)

member CreatePreconditioner : 
        transformedPreconditioner : Preconditioner<'T> -> Preconditioner<'T> 

Parameters

transformedPreconditioner  Preconditioner<T>

A preconditioner of order Order, usually constructed from TransformedMatrix.

Return Value

Use the returned preconditioner with a solver of the original matrix to preserve its residual criterion. Transpose and adjoint applications swap the row/column factors. Symmetric scaling preserves a Hermitian positive definite factor's suitability for CG/MINRES. Independent row/column scaling generally requires a general solver. The wrapped factor controls concurrent-application and refresh behavior; the adapter has no shared mutable application workspace.
