Hi,
I am quite new to Matlab and I am trying to plot an ellipse which display the centre co-ordinates, foci and the semi-major/minor axis.
I have manged to plot the ellipse and display the centre co-ordinates and the points for the foci, however the foci points are offset for some reason and I am unsure what I need to do to have them placed in the correct position.
Also I'm not sure how to start to plot the semi-major/minor axis.
I have attached the code so far.
Could I please obtain some guidance to resolve this problem.
Regards
