How to set a dynamic loop

I have an array of 85 doubles and i want to browse the array 9 by 9 (ie: for i=1:9).I want to plot then the results in a figure (3*3).

figure;

for j=1:9

BinData=ExtractContinuousData([],Info,[7],Start(j),End(j),[]);

[S1,t,f]=mtspecgramc(BinData);

subplot(3,3,j)

plot (S1,t,f);

end

%Start and End are the arrays that contains the 85 doubles each

But the problem is I just can plot the first 9 elements.How can I change each time to see the others elements?
