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.
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. The format of the Geometry Description matrix is described in the entry on decsg.
Examples
The command below starts pdetool and draws a unit circle.
