範例

>>> import numpy as np
>>> from scipy import special
>>> import matplotlib.pyplot as plt

>>> x = np.linspace(-3, 3)
>>> z = special.wofz(x)

>>> plt.plot(x, z.real, label='wofz(x).real')
>>> plt.plot(x, z.imag, label='wofz(x).imag')
>>> plt.xlabel('$x$')
>>> plt.legend(framealpha=1, shadow=True)
>>> plt.grid(alpha=0.25)
>>> plt.show()
