erf
Parameters
- const Complex &z
A complex number.
Returns
- type Complex
A complex number.
The erf, or error function, is a scaled, nonelementary integral commonly used in probability and statistics. It is defined as:
\[\DeclareMathOperator\erf{erf}
\erf(z) = \frac{2}{\sqrt{\pi}} \int_{0}^{z}e^{-t^2}dt\]
Example
Complex z = 1.0 + 1_j;
std::cout << erf(z) << "\n";
Output:
1.31615 + 0.190453j
