I need to plot the following transmission line in MATLAB I h

I need to plot the following transmission line in MATLAB. I have not got much experience with MATLAB and would like a step by step explanation if possible. What toolbox (if any) do I need to do this?

30m f=2MHz u = 1.8 x 1018 Lossless 60+j40 Zin (30) 24+j2.5

Solution

tline = rfckt.parallelplate(\'LineLength\',60,\'Width\',40);//THIS command at the MATLAB® prompt to create a circuit (rfckt) object to represent the transmission line

f = [1.0e9:1e7:2.9e9];
analyze(tline,f);// commands at the MATLAB prompt to define the range of frequencies over which to analyze the //transmission line and then run the analysis
[S_Params, Freq] = extract(tline,\'S_Parameters\');// to extract the computed S-parameter values
TrFunc = s2tf(S_Params);//to compute the transfer function from the frequency response
