Hello folks. I'm trying to port some Matlab code into C language. Currently I stuck on what Matlab defines as "LeastSquares Solution of Underdetermined System". What I need is to understand is an algorithm behind that solution. An example from Matlab documentation: Solve a system of linear equations, A*x = b Given A and b, calculate x = A\b A: 1 2 0 0 4 3 b: 8 18 x = A\b Resulting x: 0.0000 4.0000 0.6667 I realize that there should be some kind of approximation / iteration?
