Type Parameters

T

The real or complex floating-point scalar type.

Coupling inside each block is retained; entries outside the diagonal blocks are ignored. Principal blocks of a Hermitian positive definite matrix give a preconditioner suitable for ConjugateGradientSolver<T>. General nonsymmetric blocks are also supported; successful factorization alone does not certify positive definiteness.

Factors have independent storage. Call Refresh() after changing coefficients. Distinct-destination applications may run concurrently; refresh requires exclusive access.
