function pr = srinu(a)
load newfile.txt;
a=newfile(:,1);
z=xlmax1(a);
% figure(1)
%plot(z)
sum(z)
figure(2);
pr=z./1000; %you must divide by number of sample to get probability of each bin
stem(pr)% this might be your histogram according to your code
% xlabel('Bin number','FontSize',10,'FontWeight','bold');
%ylabel('Probability','FontSize',10,'FontWeight','bold');
end
