Hello, I have a small problem I wanted to build a table with the correlation of 10 images values all with the same size.

it is very simple to find correlation between two images of same size.
if you mean correlation coefficient, you can program manually the function or use corr2 :
corr2(a,b); % returns a scalar

I got scalar as output too. But if-loop is giving an error. The output should be between 1 and 2.

I think it is formula for cross correlation? If yes matlab has created build in function cross2(x,y) for correlation. Read my answer above please
