Parametrizing a rotated ellipse

I wanted to plot a rotated ellipse given by ax^2+bxy+cy^2=1 centered at (x0, y0). I searched on the net and did not find any code to do it. So, I generated it. Now, I am sharing it here.

Here are input:
If you want to plot ax^2+bxy+cy^2=1 centered at (x0, y0), it is clear for you what the input are. Also, n is the number of points in the interval [0, 2pi] considered for the parametrization.

The function gives you two vectors x and y, and you simply can plot the ellipse by using the command plot(x, y).
