DLeastSquares.dox10 The three methods discussed on this page are the SVD decomposition, the QR decomposition and normal
11 equations. Of these, the SVD decomposition is generally the most accurate but the slowest, normal
12 equations is the fastest but least accurate, and the QR decomposition is in between.

35 \section LeastSquaresQR Using the QR decomposition
37 The solve() method in QR decomposition classes also computes the least squares solution. There are
38 three QR decomposition classes: HouseholderQR (no pivoting, so fast but unstable),

186 The most accurate method to do least squares solving is with a SVD decomposition. Eigen provides one
