Form a big 2d array from multiple smaller 2d arrays

Question

The question is the inverse of this question. I\'m looking for a generic method to from the original big array from small arrays:

array([[[ 0,  1,  2],
             


        

Answer 1

I hope I get you right, let's say we have a,b :

>>> a = np.array([[1,2] ,[3,4]])
>>> b = np.array([[5,6] ,[7,8]])
    >>> a
    array([[1, 2],
           [3, 4]])
    >>> b
    array([[5, 6],
           [7, 8]])

in order to make it one big 2d array use numpy.concatenate:

>>> c = np.concatenate((a,b), axis=1 )
>>> c
array([[1, 2, 5, 6],
       [3, 4, 7, 8]])
