circ1, circ2
Purpose
circ1, circ2
Create circle geometry object.
obj = circ2
obj = circ1
obj = circ2(r,...)
obj = circ1(r,...)
Description
obj = circ2 creates a solid circle geometry object with radius 1, centered at the
origin. circ2 is a subclass of ellip2 and solid2.
obj = circ2(r,...) creates a circle object with radius r, centered at the origin. r
is a positive real scalar, or a string that evaluates to a positive real scalar, given the
evaluation context provided by the property const.
The functions circ2/circ1 accept the following property/values:
TABLE 1-7: VALID PROPERTY/VALUE PAIRS
PROPERTY VALUE DEFAULT DESCRIPTION
base corner |
center
center Positions the object either centered
about pos or with the lower left
corner of surrounding box in pos
const Cell array of {} Evaluation context for string inputs
strings
pos
Vector of [0 0] Position of the object
reals or cell
array of
strings
rot real or string 0 Rotational angle about pos (radians)
obj = circ1(...) creates a curve circle geometry object with properties as given
for the circ2 function. circ1 is a subclass of ellip1 and curve2.
Circle objects have the following properties:
TABLE 1-8: CIRCLE OBJECT PROPERTIES
PROPERTY
r
DESCRIPTION
Radius
base
Base point
x, y Position of the object
rot
Rotational angle
In addition, all 2D geometry object properties are available. All properties can be
accessed using the syntax get(object,property). See geom2 for details.
