Time for action – plotting the modified Bessel function

Let's see what the modified Bessel function of the first kind 0th order looks like:

  1. Compute evenly spaced values with the NumPy linspace() function:
    x = np.linspace(0, 4, 100)
  2. Call the NumPy i0() function:
    vals = np.i0(x)
  3. Plot the modified Bessel function with matplotlib:
    plt.plot(x, vals)
plt.show()

    The modified Bessel function will have the following output:

    Time for action – plotting the modified Bessel function

What just happened?

We plotted the modified Bessel function of the first kind 0th order with the NumPy i0() function.
