Abstract
We describe a simple hybrid numerical method for beam orbit correction in particle accelerators. The method overcomes both degeneracy in the linear system being solved and respects boundaries on the solution. It uses the singular value decomposition (SVD) to find and remove the null-space in the system, followed by a bounded linear least squares analysis of the remaining recast problem. It was developed for correcting orbit and dispersion in the B-factory rings
