CLsqFit:GetNumPtsDeleted

The GetNumPtsDeleted method returns the number of points that were manually deleted form the sample.

nPts = CLsqFit:GetNumPtsDeleted()

nPts = CLsqFit:GetNumPtsDeleted( nChannel )

n1, n2, n3, n4 = CLsqFit:GetNumPtsDeleted()

nChannel is an optional argument that specifies the channel for multi-channel (RGB) data.

nPts, n1, n2, n3, and n4 are the number of points deleted from all channels when nChannel is not specified.

The following script fits a 2x2 polynomial with data rejection enabled, then retrieves the number of points deleted and rejected from the fit.

L = new_lsqfit()	-- create a CLsqFit object
L:SetNumCoefs( {2.2} )	-- set 2x2 coefficients to fit a warped plane
L:AddPt( {3, 5}, 5.15 )	-- add a point with x = 3, y = 5, z = 5.15
-- add more points to the fit
L:DeletePt ( 2 )	-- manually delete the 2nd point
L:DoRejection( true )	-- enable bad data rejection
L:Fit()	-- Fit the polynomial
nD = L:GetNumPtsDeleted()	-- number of points deleted
nR = L:GetNumPtsRejected()	-- number of points rejected
Printf( "nDel=%d, nRej= %d\n", nD, nR )	-- list number deleted and number rejected
