make_holder()

template<typename F , typename... Args, require_not_plain_type_t< decltype(std::declval< F >()(std::declval< Args & >()...))> * = nullptr>

auto stan::math::make_holder	(	const F &	func,
		Args &&...	args
	)

Constructs an expression from given arguments using given functor.

Calls given function with given arguments.

This is similar to calling the functor with given arguments. Except that any rvalue argument will be moved to heap first. The arguments moved to heap are deleted once the expression is destructed.

Template Parameters

F	type of the functor
Args	types of the arguments

Parameters

func	the functor
args	arguments for the functor

Returns

holder referencing expression constructed by given functor

No holder is necessary if the function is not returning Eigen expression.

Template Parameters

F	type of the functor
Args	types of the arguments

Parameters

func	the functor
args	arguments for the functor

Returns
