Example of Creating a 7th Order Polynomial Fit Equation Regression With 2 columns of data- XY data where Y=F(x) | |
Open the 2D3D calculator program, select the "Analyze Raw Data" Button. | |
If you do not have XY then click on the link below. This will open a .txt
file. Choose the "save as" command.
data/hw-1.txt Choose a
place on your hard drive to save this text file. Then go to
the 2D3D Scientific Engineering Calculator program and select the "Open
Text File" command located under the "File" menu. Then select the
file you just saved to your hard drive.

This will bring you to the text import screen. The "tab" option is selected by default. Click on the OK button. | |
If you used the data shown above your screen should look like this. | |
Note that the "COL 0" option is selected by default. Hold your shift key down and select "COL 1" . | |
Next select the "2D XY" plot option | |
Your screen should now look like this. |
|
Now click on the button. | |
Your screen should look like this. The default order is 5, if you want seventh order polynomial fit, change this parameter to 7. | |
You can also change the precision of the fit, to have more accuracy. | |
The equation shows up in the white box at the bottom of the screen. Unfortunately it is not setup to do a copy and paste. This will be available in the next version of the software. |
