Maximum variable size allowed by the program is exceeded.

I want generation of codes. My program is:

Q=6;
niu=9;
K=niu+1;  
Nx=Q^K;
Vk=zeros(Nx,K);
 for j=1:1:K
     t=1; 
       for i=1:1:Nx
           Vk(i,j)=mod((Vk(i,j)+(t-1)),Q);
                 a=Q^(j-1);
              if mod(i,a)==0
                 t=t+1;
              end;                      
       end;
 end;
 Vk

It mean my massive size is 6^11X11 Can I split massive in circle? Help me please!!!

That array will require:

8*11*6^11
ans =
 3.1926e+10

Just under 32gb. To do anything with it will require a copy or few. You could either, use a smaller array, work on pieces at a time, buy more ram, or use distributed arrays on a cluster.

Thanks, but my massive's number of rows're 6^11 and columns 11 That's my problem

[Sean de Wolski]

Actually, I just gave you the number of elements above, not the memory requirements. See edit.

What are you doing? Tell us that and we can maybe help you work around this. But you're not going to be able to hold that array on a computer unless you have at minimum 32 Gb or RAM.

New my problem is the following: running files, processors cores are not load fully. How to increase the speed? P.S. I bought a powerful computer.
