VirtualArray.PolynomialFit(Array, Variable) Method

Top

Description

Uses Singular Value Decomposition to compute the coefficients of a polynomial to best fit the provided data set. The coefficients are returned in order of highest to lowest degree.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Method Signature

VirtualArray.PolynomialFit(	Array yValues,
	Variable polynomialDegree)

Arguments

yValues
Description:	The y values of the data set to be fit.

polynomialDegree
Description:	The degree of the polynomial to fit to the data.
Valid Range:	polynomialDegree > 0

Return Value

Type:

Matrix of number

Returns a row matrix of the polynomial coefficients in order of highest to lowest degree. The number of columns of the matrix will be polynomialDegree + 1.

Syntax

myMatrix1 = {1,2,3,4}.PolynomialFit(myArray1, myVariable1);
