Eureqa Enter Data Step
You can paste, view, and edit your data in the far-left tab. Entering data is very similar to using an ordinary spreadsheet application.
The Eureqa application uses a special layout:
- Each column corresponds to a single variable of your data (e.g. "time", or "oxygen concentration")
- The first row, labeled "desc" is for commenting and describing what the variable means or measured
- The second row, labeled "var" is the symbol given to each variable (e.g. "x" or "CO2")
- All remaining rows correspond to simultaneous data measurements and values
You can paste data into cells from many applications that contain spreadsheets such as Microsoft Excel, Matlab's array editor, or any tab-seperated-value text file.
Double click on a cell to edit its value. You may also enter simple expressions into a cell to generate additional variables (for example, "= x + sin(y)" will fill entire column with the numerical result of this expression on each row using the current variable symbols and values.
If your data is partitioned into discontinuous parts (e.g. two or more independent time-series or experiments), they should be seperated by a blank row. This tells the program not to smooth or differientiate across discontinuous data points.
