Why is this dot notation used?
While going over Mathworks’ 2D solution to a seven-body probelm (found here https://www.mathworks.com/help/matlab/math/solve-celestial-mechanics-problem-with-high-order-ode-solvers.html# ) the following is used, xDist = (x – x.’); where x is a row vector. My question is why the dot? I get the same result without it. That is (x – x’) = (x – x.’). I have a lot of respect for the Mathworks folks so I’m wondering if I’m missing a subtlety here.While going over Mathworks’ 2D solution to a seven-body probelm (found here https://www.mathworks.com/help/matlab/math/solve-celestial-mechanics-problem-with-high-order-ode-solvers.html# ) the following is used, xDist = (x – x.’); where x is a row vector.
