ERF Error Function
Section: Mathematical Functions
Usage
Computes the error function for real arguments. Theerf
function takes only a single argument
y = erf(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 erf function is defined by the integral:

and is the integral of the normal distribution.
Example
Here is a plot of the erf function over the range[-5,5]
.
--> x = linspace(-5,5); --> y = erf(x); --> plot(x,y); xlabel('x'); ylabel('erf(x)');
which results in the following plot.
