此函数用于计算数组元素的反正切。
句法
numpy.arcttan(array, out)
参数
- 数组：这些是要计算其反正切值的数组元素。
- 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的反正切值。
例子
import numpy as np
arr = [0, 0.3, -1]
print ("Input array : \n", arr)
arctan_val = np.arctan(arr)
print ("\nInverse tan values : \n", arctan_val)
输出
Input array :
[0, 0.3, -1]
Inverse tan values :
[ 0. 0.29145679 -0.78539816]
