pdepoly

Draw polygon

Syntax

pdepoly(x,y)
pdepoly(x,y,label)

Description

pdepoly(x,y) draws a polygon with corner coordinates defined by x and y. If the PDE app is not active, it is automatically started, and the polygon is drawn in an empty geometry model.

The optional argument label assigns a name to the polygon (otherwise a default name is chosen).

The state of the Geometry Description matrix inside the PDE app is updated to include the polygon. You can export the Geometry Description matrix from the PDE app 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 command

pdepoly([-1 0 0 1 1 -1],[0 0 1 1 -1 -1]); 

creates the L-shaped membrane geometry as one polygon.
