How can be made a matrix containing empty arrays?

Is there any possibility in Julia to have a matrix including an empty array as its element, for example as follow:

Alpha=zeros([],3,3)

The first element of Alpha is an array whose dimension isn't determined. But it gets error.
Would you please help me that how can I attain the matrix.

I'm just putting this here for posterity. Based on the comments, it sounds like you are either looking for an array of uninitialized arrays of type Int (Bogumil's comment):

alpha = [Int[] for i in 1:total_i, j in 1:total_j]  # etc. for however many dimensions

or you are looking for an n-dimensional array of type Int (Oscar's comment). For instance, a 3-dimensional array:

alpha = array{Int, 3}(undef, total_i, total_j, total_k)

Just wanted to collate the comments section into an answer in case somebody comes looking and doesn't notice the comments.
