TableCurve 3D 4.0
Introduction
TableCurve 3D gives scientists and engineers the power to find the ideal model for even the most complex data, including equations that might never have been considered.
TableCurve 3D’s built-in equation set includes a wide array of linear and nonlinear models for any application:
- Linear equations
- Polynominal and rational functions
- Logrithmic and exponential functions
- Nonlinear peak functions
- Nonlinear transition functions
- Nonlinear exponential and power equations
- User-defined functions (up to 15)
TableCurve 3D’s state-of-the-art surface fitting includes capabilities not found in other software packages:
- In addition to standard least squares minimisation, TableCurve 3D’s non-linear engine is capable of three different robust estimations: least absolute deviation, Lorentzian minimisation and Pearson VII Limit minimisation
- Option to change the maximum number of terms permitted when fitting linear equations (minimum 3; maximum 11)
- On systems that support multi-threading, TableCurve 3D’s Background Thread Processing option allows fitting to occur without any form of user input
- Option to set the default term significance anywhere from 1 to 15.
Automation Takes The Trial And Error Out Of Curve Fitting
Using its selective subset procedure, TableCurve 3D will fit 36,000 of the over 450 million built-in equations or just the ones you need — instantly. With TableCurve 3D, a single mouse click is all it takes to start the automated curve fitting process — there is no set up required! You can even enter your own specialty models to be fit and ranked along with the built-in equations. TableCurve saves you precious time because it takes the endless trial and error out of curve fitting.
Fit User-Defined Functions
Up to 15 user-defined equations can be entered and ranked along with the built-in equations. These specialised models can contain most mathematical constructs, including special functions, series convergence and conditional statements, differentiations, integrations and parameter constraints.
TableCurve 3D even offers the option of graphically adjusting equation parameters to assure convergence for the fit of user-defined models. Unlike most surface fitting programs, TableCurve 3D’s user-defined functions are compiled so they can be fitted at nearly the speed of the built-in equations. For maximum flexibility, TableCurve 3D gives you the option to save your functions as individual files, in libraries or both.
