title: MATLAB compass north
body: <p>I have a rather simple question regarding MATLAB compass plot.</p>
  
  <p>Whenever I try to plot direction using compass plot in MATLAB the 90 degree pointer always points north. Is this because the north reference in MATLAB is 90 degrees? How can I change it so the north reference is 0 degrees? This is because I'm working with windspeed vectors...</p>
