Dear Mathematica experts, How to solve, in Mathematica, the system of linear equations, when a number of equations is larger than a number of variables. Another system easily pass to apply LSM in this case, but it seems to me that there is no such opportunity in Mathematica. As an application, given N>5 points at plane, how to calculate (the parameters) of best fitting ellipse. Thanks a lot, ZL
