Detailed Description

Concept for real or complex scalar fields with real LAPACK coverage.

This is useful for algorithms such as Hermitian Lanczos where the application-space vectors may be complex, but the projected dense problem is real and only requires LAPACK support for the underlying real precision.

Template Parameters

T	Type to test.
