Hello everyone. I need to interpolate a set of 60 pairs of points associated to positions in the X axis and time. I have tried to use InterpolatingPolynomial[XMTimeM, x], but the result is a very long piecewise function. Is there another way to find the interpolating polynomial that offers a simpler way of doing this?

I need a relatively simple expression of the tipe aX^n+bX^(n-1)+.... since I will then have to write it in another language.

I will attach my code in case someone can help me.

Thanks. Jaime.
