Question

How can you perform 1-D interpolation using SciPy's interp1d function?

Answer 1

Here's an example of 1-D interpolation using interp1d:

from scipy.interpolate import interp1d
import numpy as np

# Sample data
x = np.array([0, 1, 2, 3, 4])
y = np.array([0, 1, 4, 9, 16])

# Create an interpolation function
f = interp1d(x, y, kind='linear')

# Interpolate values
x_new = np.array([0.5, 1.5, 2.5])
y_new = f(x_new)
print(y_new)
