)

Foxleg algorithm

Returns
Error returned code
0 : Correct termination
-1 : The convergence has not been reached
1 : Core problem
Parameters
[in]ndatNumber of control points
[in]nparNumber of parameters to estimate
[in]ncontNumber of additional constraints
[in]acontMatrix of additional constraints (Dimension = ncont * npar)
[in]paramCurrent values of the parameters
[in]lowerArray of lower values
[in]upperArray of upper values
[in]scaleArray of scale
[in]mautoOption_AutoFit structure
[in]flag_titlePrint the title after func_evaluate()
[in]func_evaluateFunction for evaluating the model
[in]tabexpArray of values at control points
[in]tabwgtArray of weights at control points
Remarks
The evaluation function func_evaluate() is called with the
following arguments:
ndat : Number of control points
npar : Number of parameters
param : Vector of current values for the parameters
work : Output vector for the values at control points
evaluated using the current parameter values
Some additional constraints may be applied on the parameters
When not used, we must set: ncont=0, acont=empty()
