plot_circle

Draw a circle

plot_circle(C, R, options) draws a circle on the current plot with centre C=[X,Y] and radius R. If C=[X,Y,Z] the circle is drawn in the XY-plane 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.

If C (2xN) then N circles are drawn and H is Nx1. If R (1x1) then all circles have the same radius or else R (1xN) to specify the radius of each 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
'alter', H alter existing circles with handle H

For an unfilled ellipse any MATLAB LineProperty options can be given, for a filled ellipse any MATLAB PatchProperty options can be given.
