Hello guys,
I have calculated the height of every rectangle, which are present in the image through the Pixel to micron conversion. But, i have to calculate following thing by automated loading the height previously
1) mean of height, μ = Formula (h1+h2+h3+h4)/4
2) standard deaviation for that height, σ= formula attached in the image
can you please tell me an code for that? so i can run that code to find out in my PC.
Additionally,if user only want to take 3 or 2 sample of height then can we put that condition so it can only calculate for 3 or 2 or according to user reuirements? I appreciate if you mention code for this option too.
Image attached in the comment
Thanks a lot in advance.

As you mentioned, you have the h1,h2,h3...(Already computed or known data)
mu=(h1+h2+h3+h4)/4;
And standard deaviation as per attached formula
N=4;
h=[h1,h2,h3,h4];
std_d=sqrt((1/N)*sum((h-mu)^2));

"how to load the data automatically from my previous values"
Are you asking using the previous data, like calculate B(i) using B(i-1)??
