CLsqFit:new

The new method constructs a new instance of a CLsqFit object. You must call this method before using the class.

Syntax

L = CLsqFit:new()

where

L is a new CLsqFit object with all properties initialized to default values.

The CLsqFit object is initialized with the following default properties:

n-dimensional polynomial basis function selected. See SetBasisFunc.

1 data channel. See SetNumChannels.

0 coefficients specified. See SetNumCoefs.

0 sample points added. See AddPt and AddPtWt.

Example

The following script creates a CLsqFit object, specifies a line is to be fit using 2 coefficients, adds data and does a fit. The CLsqFit object is deleted when done in order to conserve memory use.

L = CLsqFit:new()	-- create a CLsqFit object
L:SetNumCoefs( 2 )	-- set 2 coefficients
L:AddPt( 3.5, 5.15 )	-- add a point for x = 3.5, y = 5.15
L:AddPt( -12, 14 )	-- add a point
L:AddPt( -2, -4.25 )	-- add a point
L:Fit()	-- Fit the line
	-- do something with the results
L:delete()	-- best delete from memory when you are finished
