Tool fitter


get missing rank


Synopsis
deficiency(id)


Arguments

id in the id of a sub-tool
    Allowed: fitter id
    Default: 0


Returns
integer


Description
Obtain the missing rank (in SVD sense) of a fit. The constraint method will show the equations that are orthogonal to the existing ones, and which will make the solution possible.



Example
- include 'fitting.g'
- fit := fitter(n=1);		# a fitter for one real unknown
- fit.linear(dfs.functional('hyper',1),1+0*1:6, 1:6)
			# equations are x=1; x=2; ... x=6 
T
- fit.deficiency()		# missing rank
1
