"Restricted nonlinear parameter estimation, data, curve and surface fitting."
Non-linear parameter estimation software system that solves the constrained problem. Synonyms data fitting, nonlinear regression, parameter identification, curve and surface fitting is. Highly efficient numerical methods are based on Gauss-Newton-SQP algorithms.
Model modeling language functions are defined and interpreted PCOMP called and were evaluated at run time.
