Syntax
Description
pderect(xy)
draws a rectangle with corner coordinates defined by xy=[xmin xmax ymin ymax]
. If the pdetool
GUI is not active, it is automatically started, and the rectangle is drawn in an empty geometry model.
The optional argument label
assigns a name to the rectangle (otherwise a default name is chosen).
The state of the Geometry Description matrix inside pdetool
is updated to include the rectangle. You can export the Geometry Description matrix from pdetool
by selecting the Export Geometry Description . . . option from the Draw menu. For details on the format of the Geometry Description matrix, see decsg
.
Examples
The command sequence below starts pdetool
and draws the L-shaped membrane as the union of three squares.
