fitter.fitter - Function

Create a sub-tool

Synopsis
fitter(n, type, colfac, lmfac)

Arguments

n	in	number of unknowns
		Allowed:	integer
		Default:	0
type	in	type of solution
		Allowed:	coded value as string. Allowed: real, complex, separable, asreal, conjugate, with case-insensitive minimum-match
		Default:	'real'
colfac	in	collinearity factor
		Allowed:	positive float
		Default:	1e-8
lmfac	in	Levenberg-Marquardt factor
		Allowed:	positive float
		Default:	1e-3

Returns
fitter id

Description
Create a sub-tool (which can be used in the same way as a fitter tool ). This function returns an identification, which has to be used in the id argument of subsequent calls. The call can specify the standard constructor arguments (n, type, colfac, lmfac), or can specify them later in a set statement.

Example

- include 'fitting.g'
- dfit.type()
fitter 
- myfit := dfit.fitter(2)  # Create a fitter for 2 real unknowns
- dfit.fitpoly(1, 1:5, 1:5, id=myfit) # solve x+y=1; x+2y=2; ... x+5y=5
T
- print dfit.solution(id=myfit), dfit.error(id=myfit) #  show solution
[0 1]  [0 0]
