如何MPF数组？

将数组乘以mpf数即可：

import numpy as npimport mpmath as mpsmall_number = mp.besseli(400, 2)  # This is an mpf number# Note that creating a list using `range` and then converting it# to an array is not very efficient. Do this instead:A = np.arange(600)result = small_number * A  # Array of dtype object, ie, it contains mpf numbeers

逐个将包含mpf数字的两个元素数组相乘也可以：

result * result

因此，您真正的问题是如何在numpy数组中评估mpmath函数。为此，我会使用

np.frompyfunc

besseli_vec = np.frompyfunc(mp.besseli, 2, 1)besseli_vec(0, A)
