How to keep track of iterate numbers in variable names?

How to create a unique variable for the outputs of a for loop?

So for example:

for k=1:4

 product=k*3

end

I want to be able to distinguish the iterates and have a result like:

 product1=3
 product2=6
 product3=9
 product4=12

This is just a simple example, I need it for a much larger problem.

Answer 2

[Azzi Abdelmalek]

why not

 for k=1:4
 product(k)=k*3
 end

or

for k=1:4
product.(sprintf('n%d',k))=k*3
end

Answer 3

[Rick Rosson]

   N = 4;

   product = zeros(N,1);

   for k = 1:N
       product(k) = 3*k;
   end
