How do I get all the outputs of the ind2sub function ?

Say I have a variable dimension matrix A (it could have 2,3 ..n dimensions) so I could access it by A(x1,x2,...,xn). When I use a linear index 'lin_ind' how can get the matrix coordinates for that point ?

I could use

ind2sub(size(A),lin_ind)

but the problem is how to get 'all' the outputs for a variable dimension?

You can preallocate a cell array to the same size as the siz input, and use this to collect all of the outputs. This will expand to whatever size siz has:

>> idx = [3 4;5 6];
>> siz = [2,2,2];
>> out = cell(size(siz));
>> [out{:}] = ind2sub(siz,idx)
out = 
    [2x2 double]    [2x2 double]    [2x2 double]

Great. Thanks !
