I have a 4D matrix from which I am trying to extract the last column. I have tried y(1,2,2,:) but this is producing a matrix of size (1,1,1,2000) where 2000 is the length of my last index. I want the size to be (1,2000).
MATLAB Version: 8.4.0.150421 (R2014b)
Any help appreciated.
Thanks Vikrant

I do not understand the connection between your title and the content of your question. Anyway if you want to extract the last column of your 4-D matrix, it's very simple,
A_last_col = reshape(squeeze(A(:,end,:,:)),1,[]);
