reduce()

template<typename T >

template<typename T2 , typename F >

static auto stan::math::apply_vector_unary< T, require_eigen_t< T > >::reduce ( T2 &&  x, F &&  f  )

inlinestatic

Member function for applying a functor to a vector and subsequently returning a scalar.

The reduction to a scalar needs to be implemented in the definition of the functor.

Template Parameters

T	Type of argument to which functor is applied.
F	Type of functor to apply.

Parameters

x	Eigen input to which operation is applied.
f	functor to apply to Eigen input.

Returns

scalar result of applying functor to input.
