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 `pdetool` GUI 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 `pdetool` is updated to include the polygon. 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 command

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

creates the L-shaped membrane geometry as one polygon.
