fillout

Fill outside a 2-D polygon

Description

While Matlab FILL, fills inside a polygon, FILLOUT fills outside a boundary. The boundary can be a continuous line, defined by the vectors X,Y or a region defined by the 2-D arrays X,Y.

Syntax:
  H = FILLOUT(X,Y,LIM,VARARGIN)

Inputs:
  X, Y Boundary vectors (continuous) or 2-D arrays.
  LIM Outer limite box, like AXIS, ie, [minX maxX minY maxY], by default the limits of the data is used
  VARARGIN Any options of the FILL command. By default the fill color FaceColor) is green and the EdgeColor is none

A nice idea. Good help. It works as claimed. The only (minor) thing I'd change?

If nargout is 0, then do not return the handle variable h. That is, if the user does not wish to get the handle, then don't return it. All this takes is an extra 3 lines at the end:

if nargout==0
  clear h
end

Thanks. Works great.
