Freeware Downloads for "Freeware Data Fitting"
- EASY-FIT Express
- License: Freeware

The software system solves constrained nonlinear parameter estimation problems. Synonyms are data fitting, nonlinear regression, parameter identification, curve and surface fitting. The numerical methods are based on highly efficient Gauss-Newton-SQP algorithms. Model functions are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime.
General: Arbitrary fitting criteria depending on parameters to be estimated, additional nonlinear equality or inequality constraints, and optionally on a second independent model variable
Numerical routines: Gauss-Newton-type SQP methods, automatic differentiation, alternative norms (sum of absolute values, maximum of absolute values), confidence intervals for estimated parameters, correlation and covariance matrix, identification of significance...

- CurvFit
- License: Freeware

CurvFit (tm) is a curve fitting program for Windows. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked and/or valleys data. CurvFit is another improved productivity example do to using Calculus (level) programming ... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values.

Losing a set of your favorite pictures, an important document for work or school or anything else that you need can be very frustrating. Unfortunately, data loss is something that happens all of the time and there are not many people who have never lost an important file before either due to accidental deletion or something even beyond their control. Fortunately, however, when data is deleted, the space that it previously occupied is only marked as available while the original data doesn\'t change until something overwrites it.

Marketing Plan for Fortran Calculus Language, a business opportunity. For those with contacts in the Engineering & Science world this could be a great opportunity. Fortran Calculus solves most math problems within an hour or two. It's very accurrate! It's based on what is called "Automatic Differentiation" (AD). Calculus languages simplify computer coding to an absolute minimum; i.e., a mathematical model, constraints, and the objective function. Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand and not on the (numerical) process requirements to achieve an optimum solution.
