How can i change a cell to an array?

I have a 1000x1 cell consisting of 20x20x20 complex doubles.

How do i convert it such that its 1000x20x20x20?

Tried using cell2mat but ended up with 20000x20x20x20.

C{1} = rand(2,2,2) ;
C{2} = rand(2,2,2) ; 
C{3} = rand(2,2,2) ; 
C{4} = rand(2,2,2) ; 
A = cat(4,C{:}) ;

C{1}

ans = 
ans(:,:,1) =

    0.0684    0.6500
    0.4594    0.9694


ans(:,:,2) =

    0.7593    0.4700
    0.6565    0.9954

A(:,:,:,1)

ans = 
ans(:,:,1) =

    0.0684    0.6500
    0.4594    0.9694


ans(:,:,2) =

    0.7593    0.4700
    0.6565    0.9954

hi, i do not understand how this answers my question. I have a 1000x1 cell which ive attached. i would like to change it to an array of 1000x20x20x20 complex double

If C is you cell array of dimension 1x1000 with each cell 20*20*20, you can use the shown code and get A as 20*20*20*1000

that works. thank you!!
