) const
inlinevirtual

Computes the operator-multivector application.

Loosely, performs $Y = \alpha \cdot A^{\textrm{mode}} \cdot X + \beta \cdot Y$. However, the details of operation vary according to the values of alpha and beta. Specifically

  • if beta == 0, apply() must overwrite Y, so that any values in Y (including NaNs) are ignored.
  • if alpha == 0, apply() may short-circuit the operator, so that any values in X (including NaNs) are ignored.
