How to Plot Compound Interest

So I'm working on a matlab assignment to plot compound interest compounded daily with monthly contributions with yearly contribution inflation... I am just trying to get a graph of compound interest without inflation and without contributions first... This is what i have so far any help would be appreciated! Principal=5000; rate=3.25;

f(x)=Principal*(1+(rate/100)/365)^(365*x);

plot(f) I'm doing it on matlab mobile so I can't use futurevalue fxfix function.
