Vcd{1} = 125 *(1+rr{1}); %Investment in company

Vcdd{1} = Vcd{1}.*(1+rr{2});

Vcde{1} = Vcdd{1}.*(1+rr{3});

A better description of what you are trying to do would help. Why do you have so many cell arrays?

Let's say I have 3 stocks, with annual asset return (rr) = 0.2 , 0.3, 0.4 and the investment in the stock are 125 dollars per each stock.

So I want to creata a loop that calculates the Investment so for the first years it would be:

year 1 : 125 * 0.2 , 125 * 0.3 , 125 * 0.4

year 2: new value * 0.2 , new value * 0.3, new value * 0.4

year 3 : new value1 * 0.2, new value1 * 0.3, new value1 * 0.4

A simple matrix would work much better.

Vcd=125*(ones(3,10).*[1.2,1.3,1.4]').^(1:10);%this is 10 years, each column with the different rates for the year
