TableCurve 2D is an automatic selection of curve fitting and data modeling for key research.

TableCurve 2D is a professional data fitting tool that includes features not found in other software packages:

• 38 Bit Precision Mathematical Simulator for Correctly Fitting Higher Order Polynomials and rational number
• Powerful nonlinear fitting ability, effectively dealing with outlier and wide dynamic Y data range
• The AI Expert option can automatically select the appropriate peak, ion pair, or kinetic model for you

Automation eliminates repeated experiments in curve fitting

Fit all 3665 built-in equations or the equations you need for TableCurve 2D in just a few seconds! With TableCurve 2D, the automatic curve fitting process can be initiated with just a click of the mouse, without the need for any settings. TableCurve can save you valuable time as it eliminates the endless trial and error of curve fitting.

Fitting user-defined equations

You can enter up to 15 user-defined equations and arrange them together with built-in equations. These special models can contain most of the mathematical structure, including special functions, series convergence and conditional statements, differential, integral and parameter constraints. Moreover, unlike most curve fitting programs, TableCurve 2D's user-defined functions are compiled, allowing for quick execution of custom curve fitting at almost the same speed as built-in equations. You can also add up to 100 external C or FORTRAN language functions to the TableCurve 2D equation set. These equations and constraints can have infinite complexity.

Accurately infer any dataset

Using state-of-the-art AR (autoregressive) programs to improve prediction accuracy, these programs provide effective methods for inferring any dataset. Choose one of 9 different data extrapolation programs -3 for early prediction, 3 for predicting earlier data, and 3 for bidirectional prediction. Among these algorithms, six use advanced SVD and feature decomposition methods to provide in situ noise removal.
