Spot operator: opSpot/normest | Spot Home Page |
NORMEST Estimate the matrix 2-norm. normest(S) is an estimate of the 2-norm of the matrix S. normest(S,tol) uses relative error tol instead of 1e-6. [nrm,cnt] = normest(..) also gives the number of iterations used. This function is a minor adaptation of Matlab's built-in NORMEST.
