Sum up dissimilar values in a matrix

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)))

How to ensure that if any value is similar to another value, it is not added to the previous result.

Thanks for above command.

Sorry, meant to include the uniqueness in there. Edited to fix.
