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

function [k,g,gfin]=hinfsynr(p,nmeas,ncon,gmin,gmax,tol)

% [k,g,gfin]=hinfsynr(p,nmeas,ncon,gmin,gmax,tol);
% H infinity syntesis using robust control toolbox function hinfopt.
% Input and output are defined as in mu tools function hinfsyne.
