WebNov 8, 2024 · Estimates for GMRES convergence based on eigenvalue distribution often implicitly assume that the matrix is normal.Sometimes the convergence rate is still provable in an asymptotic sense in the non-normal case, but if the matrix is severely non-normal then the "pre-asymptotic" behavior will make such convergence rates never reachable in … WebJun 13, 2010 · 8,214 2 31 61. 2. +1: evalc captures all output, including fprintf calls, and it's much less risky than creating a private disp that one might later forget. – Jonas.
