In this example, we are interpolating the function f(x) = x^2 using the KroghInterpolator. We first define the x and y arrays, where x holds the data points and y holds the corresponding function values. We then create a KroghInterpolator object using the x and y arrays, and we use it to interpolate the value of f(1.5). Example 2: Interpolating a noisy function using KroghInterpolatorpython from scipy.interpolate import KroghInterpolator import numpy as np import matplotlib.pyplot as plt x = np.linspace(0, 2*np.pi, 11) y = np.sin(x) + np.random.normal(0, 0.1, 11) f = KroghInterpolator(x, y) xnew = np.linspace(0, 2*np.pi, 101) ynew = f(xnew) plt.plot(x, y, 'o', label='data') plt.plot(xnew, ynew, '-', label='interpolation') plt.legend() plt.show() ``` In this example, we are interpolating a random noisy function that is the sum of a sine function and a Gaussian noise. We first define the x and y array, where x holds the data points and y holds the corresponding function values. We then create a KroghInterpolator object using the x and y arrays, and we use it to interpolate the function values over a finer grid. Finally, we plot the original noisy data points and the interpolated values using Matplotlib.pyplot.
