CLsqFit:new

CLsqFit:new

The new method constructs a new instance of a CLsqFit object. You must call this method before using the class. Note that the object can also be created using new_lsqfit.

Syntax

L = CLsqFit:new()

Creates a default CLsqFit object and returns it as L.

L is the new instance of the CLsqFit class.

Remarks

The new CLsqFit object is initialized with the following default properties:

The n-dimensional polynomial basis function is selected. See SetBasisFunc.

1 data channel. See SetNumChannels.

0 coefficients are specified. See SetNumCoefs.

0 sample points are added. See AddPt and AddPtWt.

Data rejection is disabled.

Example

Thefollowing script creates a CLsqFit object, adds some data, and performs a fit. Since SetBasisFunc is not used, a polynomial function is assumed.

L = CLsqFit:new()	-- create a CLsqFit object
L:SetNumCoefs( 2 )	-- set 2 coefficients of the polynomial (line)
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
