FiniteCalculusGetDifference Method

Mathos Core Library 1.0.5.1 (changeset 39720)

This documentation is compiled for the latest release of Mathos Core Library

Finds the difference between terms in a sequence. By chaging the degree, we can take difference of the differences.

Syntax

public static double GetDifference(
	double[] sequence,
	int term,
	int degree
)

Public Shared Function GetDifference ( 
	sequence As Double(),
	term As Integer,
	degree As Integer
) As Double

public:
static double GetDifference(
	array<double>^ sequence, 
	int term, 
	int degree
)

static member GetDifference : 
        sequence : float[] * 
        term : int * 
        degree : int -> float

sequence: Type: SystemDouble
The sequence of doubles passed in as a double array.
term: Type: SystemInt32
The index of the first term where the diff. should be taken. NB: As the degree increases, the smaller can the term be
degree: Type: SystemInt32
The type of difference, i.e. if degree=1, the first difference is taken and if degree=2, the difference of the first difference is taken.

Type: Double
The difference between the terms in the sequence, depending on the degree.

Examples

If the sequence is {1,2,3,4,...}, term=0, degree=1, we get 1. By changning degree=2, we get 0.
