◆ dawson
Callable object computing the dawson function. \(\displaystyle D_+(x)=e^{-x^2}\int_0^{x} e^{t^2} \mbox{d}t\). Required header: Members Functions
template< value T > auto operator()( T x) const noexcept;
Parameters
Return value Returns elementwise the value of the dawson function. The result type is of the same type as the parameter. auto operator[]( conditional_expression auto cond ) const noexcept;
Higher-order function generating a masked version of eve::dawson Parameters
Return value A Callable object so that the expression Supported decorators
