This factorization is often used to solve linear least squares and eigenvalue problems. It then solves the smaller least-squares problem to get an approximate solution x'. This makes the problem convex if lambda is big enough. Step 1: form m imes l Gaussian, P_0 . If this is the work of a student for homework, sorry, but it gets a failing grade from me. These are least-squares problems, and can be solved explicitly using. However, given my loss of three hours of sleep last night, I will not be responsible for any errors which may be in the script until I have had more time to look at it more thoroughly. Depending on some parameter lambda, which again translates to the same thing, i.e. Adding a diagonal matrix to the covariance matrix, when you solve least squares. I had been I have revised one of my earlier scripts to implement the “least squares” solution in R. When I couldn't go back to sleep immediately, I lay in the dark rethinking my current math problem, in this case, the “offset matching” on which I have already posted several times. This code uses a poor choice of methods to solve the underlying least squares problem. Http://www.magiccalc.net/magiccalc/index.htm; sparseLM is a software package for efficiently solving arbitrarily sparse non-linear least squares problems. The length of the resulting residual vector is a (1 + eps) approximation of the optimal residual || A x_opt - b ||. Step 2: form n imes l matrix Q_0 st. This is a standard least squares problem and can easily be solved using Math.NET Numerics's linear algebra classes and the QR decomposition.
