erfcx

constexpr Complex erfcx(const Complex &z) noexcept: Evaluates the scaled complementary erf function, erfcx.

Parameters

const Complex &z

A complex number.

Returns

type Complex

A complex number.

This function simply evaluates \(\DeclareMathOperator\erfc{erfc} e^{z^2}\erfc(z)\).

Example

Complex z = 1.0 + 1_j;
std::cout << erfcx(z) << "\n";

Output:

0.304744 - 0.208219j
