Model Complex Data Sets Fast and Easy
What once could take days of tedious work now takes minutes, with a much more powerful result.
Find Optimum Equations to Describe Empirical Data
TableCurve 3D® 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’s built-in equation set includes a wide array of linear and nonlinear models for any application:
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.
User-Defined Fit Functions
big_residualUp 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.
The Best Fit
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.
Flexible Output Options
Output TableCurve 3D’s publication-quality graphs in black and white or color, portrait or landscape. You can also produce files containing data and equations in Lotus, Excel, ASCII, Quattro Pro and SigmaPlot formats. TableCurve 3D can speed up your programming by generating actual function code and test routines for all fitted equations in FORTRAN, C, Basic and Pascal.
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.

Applications
Quite often, substantial cost savings can be realized by optimizing process control parameters. Since TableCurve 3D automatically reports the XYZ locations for the surface’s minimum and maximum, process optimization is often a simple matter of using a single number within a TableCurve 3D report.
TableCurve is an excellent tool for examining response surfaces from designed experiments.
Create Black Box Models
At times, engineers and scientists may be faced with a highly complex process, such as human biochemistry, where underlying models are poorly defined. For such instances, TableCurve 3D can provide important insights into the subtle mechanisms in play. A successful model may suggest further experiments in synergistic pharmaco-kinetics, high energy physics or reaction chemistry.
Generate Calibration Curves
TableCurve 3D excels for those applications in the field of calibration science where an additional variable, such as temperature, influences the calibration. Whether you need to calibrate a sensor, a flow meter, wind tunnel measurements or satellite instrumentation signals, TableCurve 3D can furnish the ideal approximating function.
Produce Equations for Complex Modeling or Monte-Carlo Simulations
TableCurve 3D can be used to convert empirical data from hundreds of sources into simplified surface equations. These equations can then be input into complex models or Monte-Carlo simulations to simulate the effects of hundreds or even thousands of variables upon a given model.
Fit Tabulated Data
Frequently, scientists and engineers need to convert tables of data found in handbooks or journal publications into a simple equation, often for use in software or microcode. TableCurve 3D is capable of producing equations which preserve all or most of the accuracy present within the tabulated data. TableCurve 3D even furnishes a Precision Summary for instrument designers who must use fixed point math in their microprocessors.
Interpolate Data
There is no simpler, faster or more automated way to interpolate surface data than TableCurve 3D. Data tables or individual points are effortlessly generated for even the most demanding data sets.
Product Uses
Precisely Characterizing Changes in Surface Condition of Material Combusted in Microgravity Environment Using Ultrasonic Imaging and TableCurve 3D®
Three dimensional TableCurve 3D graphs made before-and-after combustion in Space Shuttle microgravity of a plastic specimen surface height profile that demonstrates the flame spread mechanism at work.
Surface Profiling
Precisely characterizing the changes in surface condition of material combusted in microgravity environment were made using ultrasonic imaging and TableCurve 3D. A comparison was made of the material specimens before and after microgravity combustion experiments. It was important to characterize the changed surface profile after the burn. These experiments were performed to better understand how flames spread in the microgravity environment such as would be present on the International Space Station. This type of information is critical for safety of astronauts on the Space Station.
Ultrasonic imaging technique were used to acquire precise information about the surface profile before and after the burn. This involved acquiring precise ultrasonic wave time-of-flight data across the entire surface. The time-of-flight measurements (x,y position and time-of-flight (msec)) were converted to surface depression (microns). The experiment was done on the Space Shuttle flight# STS-54. The data was then imported into TableCurve 3D for 3D viewing and data manipulation.
