Refining the Solution and Estimating Its Error: ScaLAPACK Computational Routines

This section describes the ScaLAPACK routines for refining the computed solution of a system of linear equations and estimating the solution error. You can call these routines after factorizing the matrix of the system of equations and computing the solution (see Routines for Matrix Factorization and Solving Systems of Linear Equations).
