hi,
i have matrix :
E=[1,2,5;2,3,5;3,6,5;4,6,3;4,7,6;4,11,7;4,8,11;8,12,11;5,9,6;9,13,6;13,10,6;6,10,11;6,11,7;13,14,10;14,15,10;10,15,11;11,15,12;15,16,12]
i want to write a code with "For" loop that read each rows in each iteration and attribute its element to i, j and m.
for example in first loop the result will be :
i=1 , j=2 , m=5,
in second time :
i= 2, j=3, m=5 and so on.
how should i write this ? can you help me?
thanks a lot

While it is trivial to do, it is also pointless. It's just giving the name i, j, and m to something that already exist. You may just as well use the name of that something (E) and be done with it.
Why are you asking such an odd question? What is your ultimate goal?

for K = 1 : size(E,1)
i = E(K,1);
j = E(K,2);
m = E(K,3);
%now do something with i, j, m
end
