My question is how can MATLAB divide two row vectors?

[3 3 3]/[4 5 6] is [3 3 3]*pinv([4 5 6]) to within roundoff

From the MRDIVIDE documentation: "If A is a rectangular m-by-n matrix with m ~= n, and B is a matrix with n columns, then x = B/A returns a least-squares solution of the system of equations x*A = B."
