How can i create N copies of a vector based on nonzero values in that vector?

I have a vector 1x5 which contain NZ nonzero values, what can i do if i want to create N copies of that vector such that each copy contains only 1 nonzero value from NZ?
Original Vector [1 0 5 0 3]
Copy 1 [1 0 0 0 0] Copy 2 [0 0 5 0 0] Copy 3 [0 0 0 0 3]

v = [1 0 5 0 3];
Elem = unique(v(v~=0));
nElem = numel(Elem);
Result = cell(1, nElem);
for k = 1:nElem
Result{k} = v .* (v == Elem(k));
end

Great this is very good, what if i have a 64x1 vector and i want to have 4 nonzero in each copy (of course if there is a 27 nonzero values in the original vector, the last copy will contain only 3)

not elegant but:
Original_Vector=[1 0 5 0 3];
Copy_1=Original_Vector;
Copy_1(3)=0;
Copy_1(5)=0;
etc..

I was giving that vector as an example, i don't know the index of the nonzero values, and vector might be larger than that
