How to calculate the sum of the numbers that can be divided with 12 for example in a matrix? Should I use a while or for loop?
R=randi([107 167],1,57)

You should use a mod() or rem() with logical indexing and a sum(). Were you instructed to use a loop for this exercise?

All numbers can be divided by 12. I assume you mean with no remainder, so James answer should work.

R=randi([107 167],1,57) ;
K = mod(R,12) ;
iwant = sum(R(K==0)) ;

I did it like this:
S=0;
for R=randi([107 167],1,57)
if mod(R,12)==0
S=S+R;
else S=S;
end
end
S
