此函数用于计算直角三角形的斜边。直角的斜边的计算公式为:
h = sqrt(b**2 + p**2)
其中b和p是直角三角形的底和垂直方向。
h的每个值都将复制到输出数组中。
numpy.hypot(array1, array2 out)
它返回一个数组,其中包含给定直角三角形的斜边。
import numpy as np
base = [10,2,5,50]
per= [3,10,23,6]
print("Input base array:",base)
print("Input perpendicular array:",per)
hyp = np.hypot(base,per)
print("hypotenuse ",hyp)
输出:
Input base array: [10, 2, 5, 50]
Input perpendicular array: [3, 10, 23, 6]
hypotenuse [10.44030651 10.19803903 23.53720459 50.35871325]
import numpy as np
base = np.random.rand(3,4)
per= np.random.rand(3, 4)
print("Input base array:",base)
print("Input perpendicular array:",per)
hyp = np.hypot(base,per)
print("hypotenuse ",hyp)
输出:
