How to graph 3-phase voltage using matlab?

I need to develop a MATLAB m-code that could be used to sketch the three-phase line to neutral and line-to-line voltages. I appreciate any help because I'm a beginner in MATLAB.

Please try:

   Fs = 8000;
   dt = 1/Fs;
   StopTime = 2;
   t = (0:dt:StopTime-dt)';
   N = size(t,1);

   Fc = 60;
   phi = [ -2*pi/3 0 2*pi/3 ];
   Vrms = 110;
   x = Vrms*sqrt(2)*cos(2*pi*Fc*t*ones(1,3) + ones(N,1)*phi);

   figure;
   plot(t,x);

HTH.

Fs = 50;

dt = 1/Fs;

StopTime = 2;

t = (0:dt:StopTime-dt)';

N = size(t,1);

Fc = 60;

phi = [ -2*pi/3 0 2*pi/3 ];

Vrms = 110;

x = Vrms*sqrt(2)*cos(2*pi*Fc*t*ones(1,3) + ones(N,1)*phi);

figure;

plot(t,x);
