I have a matlab function inside a jar package which is supposed to receive from my java class a double[][][]. Due the difference in the way java and matlab understand array structures when the array arrives to the matlab side it is messed.
Is there a way to convert java 3d array so then each dimension can be read like: (:,:,1) (:,:,2) and (:,:,3) in the matlab function?

As long as it arrives as a 3D variable but the dimensions seem backwards, perhaps you only need to permute it. E.g.,
x = 3D array from your java
x = permute(x,[3 2 1]); % permute to MATLAB memory ordering

Try permute(DS,[2 3 1]) to get rid of that extra transpose at the end.
The permute function does not add any elements to the input array. So if you are getting extra 0's they are there before the permute operation.
