Polynomial Interpolation for HP-67

[Matt Agajanian]

Hi all.

In the Math/Utilities module for the TI-58/59, there’s an interpolation program that fits an n-th degree polynomial to n+1 data pairs. It then allows for the calculation when an x value is entered. I would have liked to have a version of that program which would also reveal the polynomial coefficients.

I no longer have my TI-58C nor the module. So, I can’t download and print the program so I could write an HP-67 version.

Does anyone have an HP-67 or even a 29C polynomial fitting/interpolation program so I could add that to my program library?

Thanks
