I\'m converting a matlab script to python and I have it a roadblock. In order to use cubic spline interpolation on a signal. The script uses the command spline with three input
Basically you will first need to generate something like an interpolant function, then give it your points. Using your variable names like this:
from scipy import interpolate
tck = interpolate.splrep(f_o, c_signal, s=0)
and then apply this tck to your points:
c_interp = interpolate.splev(freq, tck, der=0)
For more on this your can read this post.
