error: memory exhausted or requested size too large for range of Octave's index type --

[nuncio m]

Hi list,
        Here is the code I am trying to do a PCA analysis
        
        filename='test_eof.txt';
        oufile='pc.txt';
        data="">        data1=reshape(data,25200,132);
        data2=data1';
        f=detrend(data2,0);
        R=f'*f;
        [C,L]=eig(R);
        pc1=f*C(:,1);
        pc2=f*C(:,2);
        fid=fopen(oufile,"wt");
        fprintf(fid,'%10.3f \n',pc1);
        fclose(fid);
       The code never completes the computation, it shows an error "error: memory exhausted or requested size too large for range of Octave's index type -- trying to return to prompt"
       Can anyone suggest where it goes wrong.
       Thanks
       Nuncio
