batch(xs)

Batch the arrays in xs into a single array with an extra dimension.

If the elements of xs are tuples, named tuples, or dicts, the output will be of the same type.

See also unbatch.

              [4,5,6]])
3×2 Matrix{Int64}:
 1  4
 2  5
 3  6

julia> batch([(a=[1,2], b=[3,4])
               (a=[5,6], b=[7,8])]) 
(a = [1 5; 2 6], b = [3 7; 4 8])
