% ---------- uilayout ----------%

function theResult = uilayout(theControls, theLayout, thePosition)

% uilayout -- Layout for ui controls.
%  uilayout(theControls, theLayout) positions theControls
%   according to theLayout, an array whose entries, taken
%   in sorted order, define the rectangular extents occupied
%   by each control.  TheLayout defaults to a simple vertical
%   arrangement of theControls.  A one-percent margin is
%   imposed between controls.  To define a layout region
%   containing no control, use Inf.
%  uilayout(..., thePosition) confines the controls to the
%   given normalized position of the figure.  This syntax
%   is useful for embedding controls within a frame.
%  uilayout (no argument) demonstrates itself.
