[SciPy-User] cubic spline interpolation using scipy

[Paweł Kwaśniewski]

Hi,

Once you have your spline, you can use interpolate.splev() function to
evaluate it on a given set of x values. If you look into the documentation
of this function you will see that it can also give you the derivatives -
in your case, if you want the first derivative at each point of the
interpolation, you should do the following:

dy = interpolate.splev(x,tck,der=1)

That's it.

Cheers,

Paweł
