TableCurve 2D is an automatic selection tool used for curve fitting and data modeling in critical research.

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

1. 38 bit precision mathematical simulator for correctly fitting high-order polynomials and rational numbers
2. Strong non-linear fitting ability, effectively dealing with outliers and wide dynamic Y data range
3. The AI Expert option can automatically select the appropriate peak, ion pair, or kinetic model for you

Automation eliminates repetitive experiments in curve fitting

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

Fit user-defined equations

You can input up to 15 user-defined equations and arrange them together with the built-in equations. These specialized models can contain most mathematical structures, including special functions, series convergence and conditional statements, differentiation, integration, 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 system. 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 advance 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.
