Adding to the mix of circle plotters on the File Exchange site, this function plots any number of circles of any size and x,y location. Inputs can be any logical mix of scalars, vectors, or N-D arrays. Circles can be easily formatted using LineSpec and ColorSpec name-value pairs.

Syntax
circles(x,y,r)
circles(...,'vertices',numberOfPoints)
circles(...,'rotation',degreesRotation)
circles(...,'ColorProperty',ColorValue)
circles(...,'LineProperty',LineValue)
h = circles(...)

Description
circles(x,y,r) plots circle(s) of radius or radii r centered at points given by x and y. Inputs x, y, and r may be any combination of scalar, vector, or 2D matrix, but dimensions of all nonscalar inputs must agree.

circles(...,'vertices',numberOfPoints) allows specification of how many points to use for the outline of each circle. Default value is 1000, but this may be increased to increase plotting resolution. Or you may specify a small number (e.g. 4 to plot a square, 5 to plot a pentagon, etc.).

circles(...,'rotation',degreesRotation) rotates the shape by a given degreesRotation, which can be a scalar or a matrix. This is useless for circles, but may be desired for polygons with a discernible number of corner points.

circles(...,'ColorProperty',ColorValue) allows declaration of 'facecolor' or 'facealpha' as name-value pairs. Try declaring any fill property as name-value pairs.

circles(...,'LineProperty',LineValue) allows declaration of 'edgecolor', 'linewidth', etc.

h = circles(...) returns the handle(s) h of the plotted object(s).

TIPS:
1. Include the name-value pair 'facecolor','none' to draw outlines (non-filled) circles.

2. Follow the circles command with axis equal to fix distorted circles.
