Python - 函数乘法的积分 [英] Python -the integral from function multiplication

问题描述

在 python 中，我有两个函数 f1(x) 和 f2(x) 返回一个数字.我想在它们相乘后计算一个定积分，即:

In python, I have two functions f1(x) and f2(x) returning a number. I would like to calculate a definite integral after their multiplication, i.e., something like:

scipy.integrate.quad(f1*f2, 0, 1)

最好的方法是什么?在python中甚至可能吗?

What is the best way to do it? Is it even possible in python?

推荐答案

我刚刚发现我可以使用 lambda :)

I found out just a second ago, that I can use lambda :)

scipy.integrate.quad(lambda x: f1(x)*f2(x), 0, 1)

无论如何，我要把它留在这里.也许它会帮助某人.

Anyway, I'm leaving it here. Maybe it will help somebody out.
