## ERFC Complimentary Error Function

Section: Mathematical Functions

### Usage

Computes the complimentary error function for real arguments. The`erfc`

function takes only a single argument
y = erfc(x)

where `x`

is either a `float`

or `double`

array. The output
vector `y`

is the same size (and type) as `x`

.

### Function Internals

The erfc function is defined by the integral:

and is the integral of the normal distribution.

### Example

Here is a plot of the`erfc`

function over the range `[-5,5]`

.
--> x = linspace(-5,5); --> y = erfc(x); --> plot(x,y); xlabel('x'); ylabel('erfc(x)');

which results in the following plot.
