How to find the maximum x value of a function with Python

Question

I need to find the maximum x value in Python of this function that I write through the code:

import numpy as np

y=np.abs(-np.exp(-x/1068)+np.exp(-x/46))

If I use this:

print(max(np.abs(-np.exp(-x/1068)+np.exp(-x/46))))

It prints only the maximum y value. How can I do to have also the maximum x value ?

Answer 1

如果x是一个 np.array 并且您想找到与最大y关联的x ，您可以使用np.argmax 。

x_max = x[np.argmax(y)]
