Examples
>>> 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()
