cylinder2, cylinder3
Purpose
cylinder2, cylinder3
Construction function for cylinder geometry object.
Syntax
Description
c3 = cylinder3
c2 = cylinder2
c3 = cylinder3(r,h)
c2 = cylinder2(r,h)
c3 = cylinder3(r,h,...)
c2 = cylinder2(r,h,...)
c3 = cylinder3 generates a solid cylinder object, with radius and height equal to
1, axis along the z-axis and bottom surface centered at the origin. cylinder3 is a
subclass of cone3.
c3 = cylinder3(r,h) generates a solid cylinder object with radius r and height h.
The functions cylinder3/cylinder2 accept the following property/values:
TABLE 1-12: VALID PROPERTY/VALUE PAIRS
PROPERTY VALUE DEFAULT DESCRIPTION
axis
Vector of
reals or cell
array of

reals or cell
array of
strings
rot real or string 0 Rotational angle about axis (radians)
For more information on input arguments and properties, see gencyl3.
c2 = cylinder2(...) creates a surface cylinder object, from arguments as
described for cylinder3. cylinder2 is a subclass of cone2.
