review text: Based on a roundoff error analysis, it is shown how to modify the well-known iterative refinement algorithm for nonsingular linear algebraic systems to get an algorithm for computing one of the solutions of a consistent system with quadratic singular matrix. The algorithm is given explicitly for symmetric matrices.
