用Python计算多峰下面积

import numpy as np
from scipy import integrate

def func(x):
    """定义需要计算下面积的函数"""
    return np.sin(x) + 0.5 * np.sin(2 * x)

def multi_peak_area(start, end, num_points):
    """计算多峰下面积"""
    x = np.linspace(start, end, num_points)  # 在指定范围内生成等间距的点
    y = func(x)  # 计算函数值

    # 使用梯形法则计算面积
    area = integrate.trapz(y, x)

    return area

start = 0  # 起始点
end = 2 * np.pi  # 结束点
num_points = 1000  # 采样点数量

area = multi_peak_area(start, end, num_points)
print("多峰下面积为:", area)
