plot_ellipse

Draw an ellipse on the current plot

plot_ellipse(a, ls) draws an ellipse defined by X'AX = 0 on the current plot, centred at the origin, with Matlab line style ls.

plot_ellipse(a, C, ls) as above but centred at C=[X,Y]. current plot. If C=[X,Y,Z] the ellipse is parallel to the XY plane but at height Z.

H = plot_circle(C, R, options) as above but return handles. For multiple circles H is a vector of handles, one per circle.

Options

'edgecolor' the color of the circle's edge, Matlab color spec
'fillcolor' the color of the circle's interior, Matlab color spec
'alpha' transparency of the filled circle: 0=transparent, 1=solid
