loop error

x=[1.1 2.4 3.1 4.8 5.9 6.2 7.9 8.9 9.7 10.3 11.2 12.6 13.7 14.2 15.9 16.8 17.0 18.5 19.6 20.3 21.7 22.6 23.8 24.7 25.9 26.1 27.8 28.9 29.4 30.6 31.7 32.1 33.5 34.1 35.2 36.9 37.8];
n = length(x);
L = floor(n/5);
N = n;
for a=1:N-L*4;
T=cell(a,L);
for jj = 1:L;   
   S = jj;
   n = zeros(1,floor((N-a)/(S))+1);
   for ii = 1:length(n)
       n(ii) = x(S*(ii)+(a-S));
   end
   T{a,jj} = n;
end
end

I have this code to get data from x. 'a' is the start number, I want to do a loop like 'for a=1:N-L*4',but the answer is only when a=N-L*4, there is no a=1,a=2,... What's wrong with my loop?

You're creating T on each iteration of the loop. Remove

T = cell(a,L);

and put

T = cell(N-L*4,L);

above for a=1:N-L*4.

it works!thanks!
