This MATLAB function returns the ordinary least squares solution to the linear system of equations A*x = B, i.e., x is the n-by-1 vector that minimizes the sum of squared errors (B - A*x)'*(B - A*x), where A is m-by-n, and B is m-by-1. Thus, unlike OLS, we need a probability distribution model for this to make sense.
