借助Numpy matrix.ptp()
方法,我們可以從給定矩陣沿軸獲得peek-to-peek值,即(maximum-minimum)。
用法: matrix.ptp(axis)
返回: 從給定矩陣返回peek-to-peek值
範例1:
在此示例中,我們可以看到,借助於方法,我們可以從給定矩陣中獲取peek-to-peek值matrix.ptp()
。
# 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)
輸出:
[[63] [ 9]]
範例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)
輸出:
[[ 6 6 15]]
