Iterative refinement
Iterative refinement is an iterative method proposed by James H. Wilkinson to improve the accuracy of numerical solutions to systems of linear equations.
When solving a linear system , due to the presence of rounding errors, the computed solution may sometimes deviate from the exact solution . Starting with , iterative refinement computes a sequence which converges to when certain assumptions are met.
==Description==
For , the mth iteration of iterative refinement consists of three steps:
# Compute the residual
# Solve the system
# Add the correction
