Concatenate 3 unidimensional arrays together in numpy

Question

I\'m leaving MatLab for numpy and in general it\'s going ok, but I\'m having a nightmare finding a nice pythonic way to do what would have done this in MatLab:

A         


        

Answer 1

I would use dstack

>>> A=np.array([1,2,3,4])
>>> B=np.array([5,6,7,8])
>>> np.dstack((A, B, B))
array([[[1, 5, 5],
        [2, 6, 6],
        [3, 7, 7],
        [4, 8, 8]]])
