hi. i got a problem to convert this equation into Matlab code perhaps can help me. it is about summation. thanks

this equation about summation

Answer 1

[James Tursa]

Assuming the variables are each vectors of size N:

sum((theta_bo - theta_mbo).^2) + sum((theta_to - theta_mto).^2)

[mohamad rusydi]

then how can i insert the range.? for example the range of K is from 1 to 700? aren't it important to include?

[James Tursa]

The "sum" function does this looping internally ... you don't have to manually code up a loop. E.g., the following two methods accomplish the same thing:

v = a vector of size 1 x N

% Method 1: Explicit loop
s = 0;
for k=1:N
    s = s + v(k);
end

% Method 2: Using the sum function
s = sum(v);

[Mohammad Abouali]

unless if N differs from numel(theta_bo), for some reasons. if you are summing all elements in theta_bo then you don't need to worry about the range of K. But if for some reason you are suming a portion of those vectors then just pass (1:N) to all of them. Most possibly though what James wrote here would work for you though.
