python代码实现
import numpy as np
def maxmin(array): #求每列的最值
maxlist=[]
minlist=[]
for i in range(len(array[0])):#行数
col=[]
for j in range(len(array)):#列数
col.append(array[j][i])
maxlist.append(max(col))
minlist.append(min(col))
return maxlist,minlist
if __name__=="__main__":
array = np.array([[1, 3, 4],
[0, 1, 4],
[2, 5, 6],
[2, 4, 4]])
maxlist,minlist=maxmin(array)
print(maxlist)#输出[2,5,6]
print(minlist)#输出[0,1,4]
