vTools is a toolbox for Matlab 5.3 developed within the Department of Electrical Systems and A

function mypzmap(a,b,c,d)

% does a simple pzmap plot without too many
% objects on the picture, it was necessary
% in version 6 because MvTools couln't handle 
% all the new callbacks and uicontextmenus

if size(a,1)>0,
