ellip1, ellip2
Purpose
ellip1, ellip2
Create ellipse geometry object.
Syntax
Description
obj = ellip2
obj = ellip1
obj = ellip2(a,b,...)
obj = ellip1(a,b,...)
obj = ellip2 creates a solid ellipse geometry object with center at the origin and
semi-axes equal to 1. ellip2 is a subclass of solid2.
obj = ellip2(a,b,...) creates an ellipse object with semi-axes equal to a and b,
respectively, centered at the origin. a and b are positive real scalars, or strings that
evaluate to positive real scalars, given the evaluation context provided by the
property const.
The functions ellip2/ellip1 accept the following property/values:
TABLE 1-16: 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 = ellip1(...) creates a curve circle geometry object with properties as given
for the ellip2 function. ellip1 is a subclass of curve2.
Ellipse objects have the following properties:
TABLE 1-17: ELLIPSE OBJECT PROPERTIES
PROPERTY
DESCRIPTION
a, b Semi-axes
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.
