Interpolation between 2 discret point
显示 更早的评论
Hi,
I looking for the command or a function that performan interpolation between 2 discrete point, with a polynom i defin
In fact i have a timeseries which i want to interpolate with a cubic polynom @ 0.5ms
I found the interp1 command , but i can not set the interpolation cubic coefficient polynom i want
Thanks for your reply

Why a cubic for two points ? You need 4 points to uniquely fix the cubic.

If you have coefficients then simply evaluate it using POLYVAL.
This is no longer an interpolation problem (which has the step of finding the coefficients so that the polynomial goes through the point values, but in yur case you already have the coefficients).
