Detailed Description

template<class Backend, class Scalar, class Op>
class mundy::ScaledOp< Backend, Scalar, Op >

Applies via Backend::apply(alpha, op, x, beta, y): the fused path when op provides HasScaledApplyMember, else an apply-then-axpby fallback. Holds no persistent workspace; op's own (if any) is rebuilt per apply.
