How to find computational time?

I want to find the computation time for the Add in below code. How can I do that? Is there any command?

I can use tic & toc which will give the elapsed time. but I want to find computation / execution time.

Does anyone know? Please help me.

Matlab code

A=[1 2 3 4 56  7 8 9];
B=[7 8 9 4 55  1 2 3];
tic
for i=1:length(A)
    Add(i) = A(i)+ 2* B(i);
end
toc

What is the difference between elapsed time and computation time? Of course your computer is also doing all kinds of stuff in the background and I'm not sure we can figure out the percentage of time it spent on only your MATLAB code. But what does it matter? It's the elapsed time that really matters in the real world, right?

Read about tic toc.

t1 = tic ;
A=[1 2 3 4 56  7 8 9];
B=[7 8 9 4 55  1 2 3];
for i=1:length(A)
    Add(i) = A(i)+ 2* B(i);
end
t1 = toc(t1)

t1 = 0.0289

I think you are looking for the time taken for the process to finish or to stop for one cycle. tic toc is your answer.
