erfc

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

Parameters

const Complex &z

A complex number.

Returns

type Complex

A complex number.

This function simply evaluates \(\DeclareMathOperator\erf{erf} 1 - \erf(z)\).

Example

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

Output:

-0.316151 - 0.190453j
