randomGaussian()

Generate a random number based on a Gaussian probablity distribution

Example

    circle(randomGaussian(150, 15), randomGaussian(150, 15), 25)

Syntax

randomGaussian([mean], [std])

Input	Description
mean	the mean of the distribution
std	the standard deviation of the distribution

    circle(randomGaussian(150, 50), randomGaussian(150, 50), 25)a

Description

This function picks a random value from a gaussian distribution of a specified mean µ and standard deviation σ. The gaussian distribution prefers those points around the mean more that others. The farther the point is from the mean the less likely it is to be picked. But how far? the standard deviation parameter specifies that.

$$f(x) =\frac 1 {\sigma \sqrt {2\pi}}\ e^{-\frac 1 2 (\frac {x-\mu} {\sigma})^2}$$
