此函数用于计算数组元素的反余弦。
句法
numpy.arccos(array, out)
参数
- 数组：这些是要计算其反cos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的逆cos。
例子
import numpy as np
arr = [0, 0.3, -1]
print ("Input array : \n", arr)
arccos_val = np.arccos(arr)
print ("\nInverse cos values : \n", arccos_val)
输出
Input array :
[0, 0.3, -1]
Inverse cos values :
[1.57079633 1.26610367 3.14159265]
