I'm trying to use plot, but I keep getting this error and I'm not sure why.

   n = [0:99];
  omega = 1.26 * pi;
  xn = sin(omega*n);
  plot = (n,xn);
  xlabel = ('Time Index, n');
  ylabel = ('Amplitude');
  axis = ([0 99 -1 1]);
  ??? plot = (n,xn);
               |
  Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.

Wow... what dodgy youtube "tutorial" or random teenager's blog showed that incredibly bad syntax and variable naming? Is finding the MATLAB documentation so difficult?

Show a small segment of code with which you can reproduce the error and the full text (everything in red) of the error message you receive when you execute that small segment of code.
