What is Spline Interpolation in Scipy explain with example
This recipe explains what is Spline Interpolation in Scipy with example
Recipe Objective - What is Spline Interpolation explain with example?
In Spline interpolation, the points are not fitted for a single curve likewise 1-D interpolation.
SciPy provides "UnivariateSpline()" function for that.
Example:- Find univariate spline interpolation for 3.1, 3.2... 3.9 for non linear points:
from scipy.interpolate import UnivariateSpline
import numpy as np
x = np.arange(15)
y = x**2 + np.sin(x) + 2
interpol_fun = UnivariateSpline(x, y)
new_arr = interpol_fun(np.arange(3.1, 4, 0.1))
print(new_arr)
