Array.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
