如何在matplotlib中加速动画

import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation

fig, ax = plt.subplots()
line, = ax.plot([], [])

def update(frame):
    # 更新数据
    xdata = [1, 2, 3]
    ydata = [2*frame, 3*frame, 4*frame]
    line.set_data(xdata, ydata)
    return line,

ani = FuncAnimation(fig, update, frames=range(10), interval=200)
plt.show()

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

fig, ax = plt.subplots()
line, = ax.plot([], [])

def init():
    line.set_data([], [])
    return line,

def update(frame):
    xdata = np.linspace(0, 2*np.pi, 1000)
    ydata = np.sin(2*np.pi*frame/100)
    line.set_data(xdata, ydata)
    return line,

ani = animation.FuncAnimation(fig, update, frames=range(100), init_func=init, blit=True)
plt.show()

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 1000)

fig, ax = plt.subplots()
line, = ax.plot([], [])

for i in range(100):
    line.set_data(x, np.sin(2*np.pi*i/100))
    ax.set_xlim(0, 2*np.pi)
    ax.set_ylim(-1, 1)
    plt.pause(0.001)
    ax.clear()

plt.show()
