1、numpy_r、numpy_c使用
In [1]: import numpy as np...: np.array([[1, 2, 3],[7,8,9]])
Out[1]:
array([[1, 2, 3],[7, 8, 9]])In [2]: np.array([[4,5,6],[1,2,3]])
Out[2]:
array([[4, 5, 6],[1, 2, 3]])In [3]: #按行拼接...: np.c_[np.array([[1, 2, 3],[7,8,9]]),np.array([[4,5,6],[1,2,3]])]
Out[3]:
array([[1, 2, 3, 4, 5, 6],[7, 8, 9, 1, 2, 3]])In [4]: #按列拼接...: np.r_[np.array([[1, 2, 3],[7,8,9]]),np.array([[4,5,6],[1,2,3]])]
Out[4]:
array([[1, 2, 3],[7, 8, 9],[4, 5, 6],[1, 2, 3]])
