Python| numpy matrix.ptp()
在Numpy matrix.ptp()
方法的帮助下,我们可以从给定矩阵中获得沿轴的(最大-最小) peek-to-peek值。
Syntax : matrix.ptp(axis)
Return : Return peek-to-peek value from given matrix
示例 #1:
在这个例子中,我们可以看到我们能够在方法matrix.ptp()
的帮助下从给定矩阵中获取 peek-to-peek 值。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[64, 1; 12, 3]')
# applying matrix.ptp() method
geeks = gfg.ptp(1)
print(geeks)
输出:
[[63]
[ 9]]
示例 #2:
# import the important module in python
import numpy as np
# make a matrix with numpy
gfg = np.matrix('[1, 2, 3; 4, 5, 6; 7, 8, -9]')
# applying matrix.ptp() method
geeks = gfg.ptp(0)
print(geeks)
输出:
[[ 6 6 15]]
