I am trying to plot the phase of a vibratory system with base excitation. I did the magnitude, but the phase is giving me problems. How can I make my equations so the phase equations are continuous and do not suddenly drop when the quadrant changes? atan2d does not show up with anything. Using atand shows the below result:

It should look something the phase plot on the top right of this:
