Calculates the complementary error function as defined by the following equation:
$$ \operatorname{erfc}(z)=1-\frac{2}{\sqrt{\pi}} \int_{0}^{z} \exp \left(-t^{2}\right) d t $$

Description |
|---|---|
|
out=erfc(z); |
Returns the complementary error function of z where z is a scalar number or matrix of scalar numbers. |
Example
Plot the complementary error function from z=-5 to 5.
z=linspace(-5,5,50); # generate vector of numbers from -5 to 5 with 50 points erfc_z = erfc(z); plot(z,erfc_z,"z","erfc");
The following figure shows the plot created by the example code.
