i m trying to calculate accuracy of a system using SVM in libsvm, svmtrain makes a model , but svmpredict output files are empty..my program is..

trr=<408x11264 double>
tss=<204x11264 double>
users=102;
t1=4;
t2=2;
function P=svm_g3(trr,tss,users,t1,t2)
addpath(genpath('E:\libsvm-3.18\matlab'))
ltr=[];
for i=1:users
    for j=1:t1
        ltr=[ltr;i];
    end
end
lts=[];
for i=1:users
    for j=1:t2
        lts=[lts;i];
    end
end
      mod=svmtrain(ltr,trr,'-t 0 -b 1 d 3');
      [a1,a2]=svmpredict(lts,tss,mod);
      P=a2(1);
