此函数用于计算数组元素的反正弦值。
句法
numpy.arcsin(array, out)
参数
- 数组:这些是要计算其反正弦值的数组元素。
- Out:这是输出数组的形状。
返回
它返回一个数组, 其中包含所有数组元素x的反正弦值。
例子
import numpy as np
import math
arr = [0, 0.3, -1]
print ("Input array : \n", arr)
arcsine = np.arcsin(arr)
print ("\nInverse Sine values : \n", arcsine)
输出
Input array :
[0, 0.3, -1]
Inverse Sine values :
[ 0. 0.30469265 -1.57079633]
