converting values in cell array

I have a cell array A A = [(1 2 3), (5 6 7), (13 14 15)]

I want to convert it so it count sequentially and creates another cell array

B = [(1 2 3), (4 5 6), (7 8 9)]

thanks

I can't imagine a use-case for this, but here you go:

A = {[1,2,3],[5,6,7],[13,14,15]};
B = cell(size(A));
counter=0;
for iter = 1:numel(A),
    B{iter} = counter + (1:numel(A{iter}));
    counter=counter + numel(A{iter});
end

Hope this helps.
