select() [3/6]

template<typename T_true , typename T_false , typename T_return = return_type_t<T_true, T_false>, typename T_true_plain = promote_scalar_t<T_return, plain_type_t<T_true>>, typename T_false_plain = promote_scalar_t<T_return, plain_type_t<T_false>>, require_all_container_t< T_true, T_false > * = nullptr, require_all_same_t< T_true_plain, T_false_plain > * = nullptr>

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

inline

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

Eigen expressions are evaluated so that the return type is the same for both branches.

Both containers must have the same plain type. The scalar type of the return is determined by the return_type_t<> type trait.

Overload for use with two containers.

Template Parameters

T_true	A container of stan Scalar types
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.
