◆ erfcx
Callable object computing the normalized complementary error function \(\mbox{erfcx}(x) = e^{x^2} \mbox{erfc}(x)\). Required header: Members Functions
Definition: value.hpp:103 Parameters Return value Returns elementwise \(\displaystyle \mbox{erfcx}(x)=\frac{2e^{x^2}}{\sqrt\pi}\int_{x}^{\infty} e^{-t^2}\mbox{d}t\) The result type is of the same type as the parameter. auto operator[]( conditional_expression auto cond ) const noexcept;
