Hi All,
I have a 12*12 matrix and want to add the entries of matrix which are not equal to 1 and which are not similar to any other value in the Matrix. In short, I want to add up all the dissimilar values and the values not equal to 1.
Is there any short way to do so using loop function.
Many Thanks
Anum

If M is your array ...
sum(unique(M(M~=1)))
