What TableCurve 2D is
TableCurve 2D is Windows desktop software for engineers and researchers who need automated curve fitting and equation discovery. It fits thousands of built-in linear and nonlinear equations, including polynomial, rational, peak, transition, and kinetic models. An AI Expert option can choose peak, transition, or kinetic models for fitting. The software includes a 38-digit precision math emulator and robust nonlinear fitting methods for outliers and broad Y-data ranges. Data tools provide smoothing, denoising, autoregressive prediction and extrapolation, spline estimation, and local regression. Tables support up to 65,536 points, while an averaging digital import filter can handle up to 16.4 million points. Imports include ASCII, Excel, Lotus, Quattro, SigmaPlot, DIF, SPSS, Systat, and dBase. Reports can go to Word or RTF, with numeric output to Excel. Batch automation processes multiple datasets, and generated function code can target Fortran, C, Visual Basic, QBasic, and Pascal. Pricing is available by request.
