select() [6/7]

template<typename T_bool , typename T_true , typename T_false , require_eigen_array_vt< std::is_integral, T_bool > * = nullptr, require_all_stan_scalar_t< T_true, T_false > * = nullptr>

auto stan::math::select ( T_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 with an Eigen object of booleans, and two scalars.

The chosen scalar is returned as an Eigen object of the same dimension as the input Eigen argument

Template Parameters

T_bool	type of Eigen boolean object
T_true	A stan Scalar type
T_false	A stan Scalar type

Parameters

c	Eigen object of boolean condition values.
y_true	Value to return if condition is true.
y_false	Value to return if condition is false.
