Use the sum command and vectorized operations: sum ( (x-mean (x))* (y-mean (y))) The key revelation here is that the sum function is just taking the sum over the argument (vector, matrix, whatever). In this case, it's sufficient to give it a vector, and in this case, the vector expression is a little more complicated than sum (z), but notice ...If you are a developer with not enough knowledge in math, you might be having hard time grasping the basic formula of Reinforcement Learning. Understanding this equation might be challenging for people with insufficient mathematical background. However, aside from the cryptic symbols, it is not that hard to understand.To write the parametric equation of a line through two points X0 and X1 in \R3, we take U = X1 − 0 in , which yields X = X0 + t(X1 − X0) = tX1 + (1 − t)X0, − ∞ < t < ∞. The line segment from X0 to X1 consists of those points for which 0 ≤ t ≤ 1. These familiar notions can be generalized to \Rn, as follows:Solve Boolean equations. Compute truth tables.
