function [varargout] = unix(varargin)
%UNIX   Execute UNIX command and return result.
%   [status,result] = UNIX('command'), for UNIX systems, calls upon
%   the operating system to execute the given command.  The resulting
%   status and standard output are returned.
%
%   Examples:
%
%       [s,w] = unix('who')
%
%   returns s = 0 and, in w, a MATLAB string containing a list of
%   the users currently logged in.
%
%       [s,w] = unix('why')
%
%   returns a nonzero value in s to indicate failure and sets w to
%   the null matrix because "why" is not a UNIX command.
%
%       [s,m] = unix('matlab')
%
%   never returns because running the second copy of MATLAB requires
%   interactive user input which cannot be provided.
%
