Hi, A new version of the vector fitting routine (vectfit.m) has been implemented that has far better convergence properties than the old one. Also, the computational efficiency has been significantly improved due to sparse implementation and usage of Normal Equations. The new version is included in package vfit2.zip, downloadable from http://www.energy.sintef.no/Produkt/VECTFIT/index.asp Any bugs/problems should be reported.
