if_else() [1/4]

template<typename T_true , typename T_false >

return_type_t< T_true, T_false > stan::math::if_else ( const bool  c, const T_true  y_true, const T_false  y_false  )

inline

Return the second argument if the first argument is true and otherwise return the second argument.

This is just a convenience method to provide a function with the same behavior as the built-in ternary operator. In general, this function behaves as if defined by

if_else(c, y1, y0) = c ? y1 : y0.

Template Parameters

T_true	type of the true argument
T_false	type of the false argument

Parameters

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