    Understanding Solutions and Singular Matrices

    I'll look into the simplex method. Hopefully the answers will be close enough. This is a non-linear least squares problem, and I don't need an exact solution. I only need the statistically least wrong solution. Or a decent approximation. I'm trying to use QR Decomposition to solve the systems...

    Understanding Solutions and Singular Matrices

    Yeah, I'm doing nonlinear minimization of squares in relation to a reference point. Maybe this is the part I don't really understand. I get that I have a set of n spheres (where n > 4) and 3 unknowns. I can figure out the residual equations, and compute the differentials. I understand that we...

    Understanding Solutions and Singular Matrices

    I'm in touch with the author. The C++ code is actually proprietary and controlled by the mining company who commissioned it. My first instinct was also to examine it directly. Porting C++ to java is trivial. The matrices may be poorly conditioned. Unfortunately my real-world data may be poorly...

    Understanding Solutions and Singular Matrices

    Hey folks. I'm working on a project which seems to be encountering a problem. I took Linear Algebra a few years ago in college, and haven't really applied it very much so I'm at a bit of a loss here. I have a solution to a iterative nonlinear least squares problem: Trilateration with n...
