Public Methods

Method	Description
Differentiate ( Primitive array ) : Primitive	Calculate the derivative of a 1D data array.
DistBinomial ( Primitive n, Primitive p ) : Primitive	Create an array with a Binomial distribution. This is like the probablity of getting k heads from 20 (n) coin tosses, with a probablity for each toss getting a heads of 0.5 (p).
DistNormal ( Primitive distMean, Primitive distSTD, Primitive size ) : Primitive	Create an array with a Normal distribution.
DistTriangular ( Primitive rangeMin, Primitive rangeMax, Primitive size ) : Primitive	Create an array with a Triangular distribution.
DistUniform ( Primitive rangeMin, Primitive rangeMax, Primitive size ) : Primitive	Create an array with a Uniform distribution.
Frequency ( Primitive array, Primitive bins, Primitive normalised ) : Primitive	Calculate a frequency distribution from array of data.
Integrate ( Primitive array ) : Primitive	Calculate the integral of a 1D data array.
InterpolateX ( Primitive array, Primitive y ) : Primitive	Interpolate a 1D data array to find the value of x(y). The values of y should be monotonically increasing with x.
InterpolateY ( Primitive array, Primitive x ) : Primitive	Interpolate a 1D data array to find the value of y(x). The values of x should be monotonically increasing.
SetArray ( Primitive array ) : Primitive	Set a 1D array of numbers to perform some statistics on. This command must be called before any statistics are calculated.

Method Details

Differentiate() public static method

Calculate the derivative of a 1D data array.

public static Differentiate ( Primitive array ) : Primitive
array	Primitive	The array to differentiate (array[x]=y).
return	Primitive

DistBinomial() public static method

Create an array with a Binomial distribution. This is like the probablity of getting k heads from 20 (n) coin tosses, with a probablity for each toss getting a heads of 0.5 (p).

public static DistBinomial ( Primitive n, Primitive p ) : Primitive
n	Primitive	The number of tries.
p	Primitive	The probablity of success for each try.
return	Primitive

DistNormal() public static method

Create an array with a Normal distribution.

public static DistNormal ( Primitive distMean, Primitive distSTD, Primitive size ) : Primitive
distMean	Primitive	The mean of the distribution.
distSTD	Primitive	The standard deviation of the distribution.
size	Primitive	The number of points.
return	Primitive

DistTriangular() public static method

Create an array with a Triangular distribution.

public static DistTriangular ( Primitive rangeMin, Primitive rangeMax, Primitive size ) : Primitive
rangeMin	Primitive	The minimum value.
rangeMax	Primitive	The maximum value.
size	Primitive	The number of points.
return	Primitive

DistUniform() public static method

Frequency() public static method

Calculate a frequency distribution from array of data.

public static Frequency ( Primitive array, Primitive bins, Primitive normalised ) : Primitive
array	Primitive	The array to create the frequency distribution from.
bins	Primitive	The number of bins spanning the data.
normalised	Primitive	Is the frequency normalised to integrate to 1 ("True" or "False").
