%
% Usage
%
% When making a function call, it is possible to assign
% multiple outputs in a single call, (see, e.g., max for
% an example). The deal call allows you to do the
% same thing with a simple assignment. The syntax for its
% use is
%
% [a,b,c,...] = deal(expr)
%
% where expr is an expression with multiple values. The simplest
% example is where expr is the dereference of a cell array, e.g.
% expr <-- A{:}. In this case, the deal call is equivalent
% to
%
% a = A{1}; b = A{2}; C = A{3};
%
% Other expressions which are multivalued are structure arrays with
% multiple entries (non-scalar), where field dereferencing has been
% applied.
