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
.
