Python numpy中的ravel()、flatten()、reshape(-1)將多維array轉換成一維

參考:numpy中的ravel()、flatten()、squeeze()的用法与区别

import numpy as np
ary = np.arange(12).reshape(3,4)
print(“ary:\n”,ary)
print(“ravel:\n”,ary.ravel())
print(“flatten:\n”,ary.flatten())
print(“reshape(-1):\n”,ary.reshape(-1))

print(‘ravel(“F”):\n’,ary.ravel(“F”))
