pdecirc - Draw circle
Syntax
pdecirc(xc,yc,radius)
pdecirc(xc,yc,radius,label)
Description
pdecirc(xc,yc,radius) draws
a circle with center in (xc,yc) and radius radius.
If the pdetool GUI is not active, it is automatically
started, and the circle is drawn in an empty geometry model.
The optional argument label assigns a name
to the circle (otherwise a default name is chosen).
The state of the Geometry Description matrix inside pdetool is
updated to include the circle. You can export the Geometry Description
matrix from pdetool by using the Export
Geometry Description option from the Draw menu.
For a details on the format of the Geometry Description matrix, see decsg.
Examples
The following command starts pdetool and
draws a unit circle.
pdecirc(0,0,1)
