Draw ellipse.
Synopsis
pdeellip(xc,yc,a,b,phi)
pdeellip(xc,yc,a,b,phi,label)
Description
pdeellip(xc,yc,a,b,phi)
draws an ellipse with center in (xc,yc) and semiaxes a and b. The rotation of the ellipse (in radians) is given by phi. If the pdetool GUI is not active, it is automatically started, and the ellipse is drawn in an empty geometry model.
The optional argument label assigns a name to the ellipse (otherwise a default name is chosen.)
The state of the Geometry Description matrix inside pdetool is updated to include the ellipse. You can export the Geometry Description matrix from pdetool by selecting 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 an ellipse.
