finding the max of a column in an array

Question

def maxvalues():        
for n in range(1,15):
    dummy=[]
    for k in range(len(MotionsAndMoorings)):
        dummy.append(MotionsAndMoorings[k][n])
    max(dummy         


        

Answer 1

An example with a random input array, showing that you can take the max in either axis easily with one command.

import numpy as np

aa= np.random.random([4,3]) 
print aa
print
print np.max(aa,axis=0)
print
print np.max(aa,axis=1)

Output:

[[ 0.51972266  0.35930957  0.60381998]
 [ 0.34577217  0.27908173  0.52146593]
 [ 0.12101346  0.52268843  0.41704152]
 [ 0.24181773  0.40747905  0.14980534]]

[ 0.51972266  0.52268843  0.60381998]

[ 0.60381998  0.52146593  0.52268843  0.40747905]
