TableCurve 3D’s state-of-the-art surface fitting includes capabilities not found in other software packages:
Automation Takes The Trial And Error Out Of Curve Fitting
Using its selective subset procedure, TableCurve 3D will fit 36,000 of the over 450 million built-in equations or just the ones you need – instantly. With TableCurve 3D, a single mouse click is all it takes to start the automated curve fitting process – there is no set up required! You can even enter your own specialty models to be fit and ranked along with the built-in equations. TableCurve saves you precious time because it takes the endless trial and error out of curve fitting.
Up to 15 user-defined equations can be entered and ranked along with the built-in equations. These specialized models can contain most mathematical constructs, including special functions, series convergence and conditional statements, differentiations, integrations and parameter constraints. TableCurve 3D even offers the option of graphically adjusting equation parameters to assure convergence for the fit of user-defined models. Unlike most surface fitting programs, TableCurve 3D’s user-defined functions are compiled so they can be fitted at nearly the speed of the built-in equations. For maximum flexibility, TableCurve 3D gives you the option to save your functions as individual files, in libraries or both.
Visually Discover the Best Equation to Model your Data: Graphically Review Surface Fit Results
Once your XYZ data have been fit, TableCurve 3D automatically sorts and plots the fitted equations by the statistical criteria you select (r2, DOF adjusted r2, Fit Standard Error or the F Statistic). Graphically review the fitted results as you scroll through the equation list. 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.
Viewing a surface fit from all angles is imperative in determining whether or not a given fit is accurate. Using a simple interface, TableCurve 3D lets you view a graph from any angle. It will even animate the graph automatically in a specified XY and/or Z angle sequence. Just sit back and observe every nuance within the fit. TableCurve 3D gives you all of the tools you need to discover the model that best meets your requirements for the ideal fit.
输出TableCurve 3D的黑色和白色或彩色，纵向或横向的出版质量的图形。 您还可以在Lotus，Excel，ASCII，Quattro Pro和SigmaPlot格式中生成包含数据和方程式的文件。 TableCurve 3D可以以FORTRAN，C，Basic和Pascal语言为所有拟合方程生成实际的功能代码和测试例程来加快编程速度。
All This Power - and Still Easy to Use!
TableCurve 3D takes full advantage of the Windows graphical user interface to simplify every aspect of operation – from data import to output of results. Import data from many popular file formats including SigmaPlot, Excel, Lotus, SPSS and ASCII. Once your data are in the TableCurve editor, start the automatic fitting process with a single mouse click. Choose to fit all equations, select a group of equations or create a custom equation set. All equations are readily available from the Toolbar or TableCurve’s Process Menu. You can even set up TableCurve 3D to begin fitting the moment data are imported or modified with Background Thread Processing Fitting. Users consistently comment that – out of the box, without reading the instructions – TableCurve is highly intuitive, easy-to-use and remarkably simple to learn.
