A little idea about big experiment data

% Calculate the irregularity of the directly measured quantity , Input parameters are data matrix and B Class component 
%tp Is the correction factor ,n Is the number of measurements 
tp=[1.84000000000000,1.32000000000000,1.20000000000000,1.14000000000000,1.11000000000000,1.09000000000000,1.08000000000000,1.07000000000000];
n=size(A,1);
uc=sqrt((sqrt(var(A)/(n-1))*tp(n-1))^2+ub^2);
ur=uc/mean(A)*100;
disp(uc);
disp(ur);
end
 You can help test , See if there's a problem ~
