Write a function that will receive a variable number of input arguments: the length and width of a rectangle, and possibly also the height of a box that has this rectangle as its base

boxcalcs.m

function [area, varargout] = boxcalcs(len, wid, varargin)

% Calculates a rectangle area and possibly also a

% height of a box and returns the area and possibly volume

% Format of call: boxcalcs(length, width) or

% boxcalcs(length, width, height)

% Returns area of box and if height is passed, volume

% always return the area

area = len * wid;

n = nargin;

% if the height was passed, return the box volume

if nargin == 3

 varargout{1} = area * varargin{1};

end

end
