Numpy 中clip函数的使用
numpy.clip(a, a_min, a_max, out=None)
Clip (limit) the values in an array.
Given an interval, values outside the interval are clipped to the interval edges. For example, if an interval of [0, 1] is specified, values smaller than 0 become 0, and values larger than 1 become 1.
一维数组
其中a是一个数组，后面两个参数分别表示最小和最大值
import numpy as np x=np.array([1,2,3,5,6,7,8,9]) np.clip(x,3,8)Out[88]:array([3, 3, 3, 5, 6, 7, 8, 8])12345
多维数组
x=np.array([[1,2,3,5,6,7,8,9],[1,2,3,5,6,7,8,9]])
np.clip(x,3,8)
Out[90]:
array([[3, 3, 3, 5, 6, 7, 8, 8],
[3, 3, 3, 5, 6, 7, 8, 8]])
