How to find position (indices) of minimum element on each page of 4 dimensional matrix?

I have 4 dimensional vector similar to that shown in attached picture. I want to find position (indices) of minimum on every page separately. For example for 2 dimension we can do like this,

[i, j]=find(A == min(min(A)));

Similar thing i want to do for 4 dimensional vector. Is there any solution using MATLAB?

You can use the function min to achieve this. Read about it.

% demo data using 3D matrix 
A(:,:,1) = [2 4; -2 1];
A(:,:,2) = [9 13; -5 7];
A(:,:,3) = [4 4; 8 -3];
[val,idx] = min(A,[],[1 2],'linear') ;   % gives min value and global index 
[i,j,k] = ind2sub(size(A),idx) ;         % get sub index from global index 

idx gives you the global index, you can convert them into sub index using ind2sub. Read about this function.
