此函数用于计算数组元素的双曲反正弦。
句法
numpy.arcsinh(array[, out] )
参数
- 数组:要计算其双曲反正弦值的数组元素(以弧度为单位)。
- out:输出数组的形状。
返回
返回包含双曲反正弦值的数组。
例子
import numpy as np
import math
arr = np.array([0, math.pi/4, 3*math.pi/2, math.pi/6])
print("Input Array:", arr)
print("tanh Array:", end=" ")
arcsinharr = np.arcsinh(arr)
print(arcsinharr)
输出
Input Array: [0. 0.78539816 4.71238898 0.52359878]
tanh Array: [0. 0.72122549 2.25441459 0.50221899]
