Model Complex Data Sets Fast and Easy
What once could take days of tedious work now takes minutes, with a much more powerful result.
Find Optimum Equations to Describe Empirical Data
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 minimization, TableCurve 3D’s non-linear engine is capable of three different robust estimations: least absolute deviation, Lorentzian minimization and Pearson VII Limit minimization.
- 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.
