I have two questions

first how i plot impedance on smithchart . I have a vector of impedance values against a vector of frequency

i used smithplot(freq,zin) but smith chart has a radius of 1 so I divided zin/max(zin). Is there another way

second question how to add title to smithplot figure

title('impedance') doesn't work

You can add the title of smithplot using SmithPlot Properties. For example,

S = read(rfckt.amplifier,'passive.s2p');

ports = [1,1;1,2];

s = smithplot(S,ports);

s.TitleTop = 'title'
