TableCurve 3D is the first and only program that combines a powerful surface fitter with the ability to find the ideal equation to describe three dimensional empirical data. It 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 gives you all of the tools you need to discover the model that best meets your requirements for the ideal fit. It also offers advanced non-parametric procedures for gridded and scattered data. TableCurve 3Dís state-of-the-art surface fitting includes capabilities not found in other software packages:

  • In addition to standard least squares minimization, TableCurve 3Dís non-linear engine is capable of three different robust estimations are least absolute deviation, Lorentzian minimization and Pearson VII Limit minimization
  • Option to change the maximum number of terms permitted when fitting linear equations.
  • On systems that support multi-threading, TableCurve 3Dís Background Thread Processing option allows fitting to occur without any form of user input

A 3D residuals graph as well as parameter output are generated for each fitted equation. Add confidence or prediction intervals to the graph to detect outliers in your data. You can also automatically display a 2D contour plot on the top and bottom of the surface fit graph to get another view of your data. Data, statistical and numeric summaries are also available from within the Review Surface Fit window so you can further analyze fit results.

TableCurve 3Dís 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 is very much usefull to solve the complexity in Science and Engineering Problems :

  • Optimize product and process performance
  • Quickly calibrate sensors
  • Understand complex chemical kinetics
  • Reduce empirical data to a simple equation
  • Stabilize systems with dynamic feedback
