I have used both 5.3 and 6.1 matlab verisons. Coul you please help in making it working. If not you please send some echo paths. thanks in advance satyanarayana --- In echocancel@y..., "Shiv Garg, Gurgaon." <shivg@g...> wrote: > Hi all ! > I hope this fw mail will solve your problem. > Also there is a function, impresp available with room software. try using > it.
