Hi all,
I am new to MATLAB and currently I am playing around with plots and I am struggling with finding one for the following. From my data, I have evaluated the ellipse equation:
0.211*x^2-0.157*x*y+0.065*y^2=1
An approach would involve to convert this equation into the parametric form, but I wonder whether this could be directly plotted.

请先登录，再回答此问题。
