select() [5/6]

template<typename T_true , typename T_false , typename ReturnT = promote_scalar_t<return_type_t<T_true, T_false>, plain_type_t<T_false>>, require_stan_scalar_t< T_true > * = nullptr, require_container_t< T_false > * = nullptr>

ReturnT stan::math::select ( const bool  c, const T_true  y_true, const T_false  y_false  )

inline

If first argument is true return the second argument, else return the third argument.

Overload for use when the 'true' return is a scalar and the 'false' return is a container

If chosen, the scalar is returned as a container of the same size and plain type as the provided argument. Consequently, any Eigen expressions are evaluated.

Template Parameters

T_true	A stan Scalar type
T_false	A container of stan Scalar types

Parameters

c	Boolean condition value.
y_true	Value to return if condition is true.
y_false	Value to return if condition is false.
