matlab code for measuring S parameter using VNA through USB-GPIB

I have some problems with the matlab code for using VNA to measure S parameter using USB-GPIB.

 

VNA = instrfind('Type', 'gpib', 'BoardIndex', 8, 'PrimaryAddress', 16, 'Tag', '');

if isempty(VNA)

  VNA = gpib('agilent', 8, 16);

else fclose(VNA);

  VNA = VNA(1);

end

frequency_start=2e9;

frequency_stop=3e9;

 

I am now doing a project involving measuring the s parameter.

I will appreciate anyone who can provide me a sample matlab code.
