Program working on one PC but not on other

In a program to calculate value at risk. The for loop is stuck on a particular iteration 41 out of 50 iterations. But on some machines it is working fine.

Is there a problem of memory allocation or something else?

The error is coming is following function

function z2 = myfunction(r1,x1,x2)
warning('off', 'stats:gpfit:EvalLimit');
[bootstat,bootsam] = bootstrp(50,[],r1); %Sampling With Replacement from r1
Z=sort(r1(bootsam));% bootsam is the indices and Z1(bootsam) is 50 sample drawn  
temp = [];
for k1 = x1:.1:x2
a5=0;
for i = 1:50
      y5=Z(:,i);
    [f12,x12]=ecdf(y5);                                                                                                              
     f12=f12(2:end);
     x12=x12(2:end);
     k11=k1;
    
     k1 = min(k1,(y5(end-500))); % this is due to the possibility that the threshold could be greater than y(end-500)
     % at least 500 observations are required to calculate Non-subjective Value-at-Risk
    
    y5(y5<=k1)=[];
    para = gpfit(y5-k1);
    [h7, h8] = size (y5>k1);
    h4=min(find(y5>k1));
    [h5, h6] = size (y5);
    s5=0;
    clear F1 F2 F3 g;
    for j5=h4:h5
        
        F1=1-interp1q(x12,f12,y5(j5));
        F2=1-interp1q(x12,f12,k1);
        F3 = F1/F2;
        g = 1-gpcdf(y5(j5)-k1,para(1), para(2), 0);
        s5=s5+(g-F3)^2;
     end
 a5=a5+(s5/h7);
end
temp = [temp; [k1 a5]];
k1=k11;
end
[M,I]= min(temp(:,2));
z2=temp(I,1);
end

What is the exact error message?

I don't see j6 anywhere in the code you posted, so the output is a bit strange. Did you try using breakpoints?

[Nikhil Gupta]

Yes, when I use breakpoints, program is running fine. But the program is not working in one go without breakpoints, strange. And j6 is present in the main program from where this function is called.
