new_lsqfit

new_lsqfit

The new_lsqfit is a non-class version of the CLsqFit:new method which creates and returns a newa CLsqFit object.

Syntax

L = new_lsqfit()

L is returned as the new CLsqFit object.

On failure, nil is returned.

Remarks

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

The n-dimensional polynomial basis function 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

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

L = new_lsqfit()	-- create 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
