Simultaneous Changing of Values in For Loop.

Can I change two values at once in a for loop or any other way in MATLAB?

As an example:

t=0;

for (i=1:1:3)&(j=2:1:4)

k=i*j;

t=t+k;

end

I know this code is wrong but is there a way to simlateously increament i and j values!

i=1 and j=2

k=2

t=2

then

i=2 and j=3

hence

k=6

and t=2+6=8

like that???

Usually it is much easier to increment over indices, not data:

t0 = 0;
t  = t0;
Iv = 1:1:3;
Jv = 2:1:4;
for x = 1:numel(Iv)
    k = Iv(x)*Jv(x);
    t = t+k;
end

In your case the loop is entirely superfluous anyway:

t = t0 + cumsum(Iv.*Jv)

The system I had to solve was much more complex than this. Though this is the solution to the example but cuoldn't be applied directly to my system. Nonetheless, it did definitely help me and did solve my system.

Thank you.
