%HELP On-line help, display text at command line. 
%   HELP, by itself, lists all primary help topics.  Each primary topic
%   corresponds to a directory name on the MATLABPATH.
%
%   "HELP TOPIC" gives help on the specified topic.  The topic can be a
%   command name, a directory name, or a MATLABPATH relative partial
%   pathname (see HELP PARTIALPATH).  If it is a command name, HELP
%   displays information on that command.  If it is a directory name,
%   HELP displays the Table-Of-Contents for the specified directory.
%   For example, "help general" and "help matlab/general" both list
%   the Table-Of-Contents for the directory toolbox/matlab/general.
%
%   HELP FUN displays the help for the function FUN.
%
%   T = HELP('topic') returns the help text in a '\n' separated string.
%
%   LOOKFOR XYZ looks for the string XYZ in the first comment line
%   of the HELP text in all M-files found on the MATLABPATH.  For all 
%   files in which a match occurs, LOOKFOR displays the matching lines.
%
%   MORE ON causes HELP to pause between screenfuls if the help text
%   runs to several screens.
%
%   In the online help, keywords are capitalized to make them stand
%   out.  Always type commands in lowercase since all command and
%   function names are actually in lowercase.
%
%   For tips on creating help for your m-files 'type help.m'.

%   Tips for creating help for your m-files:
%
%   HELP MFILENAME displays the first set of contiguous comment lines in
%   an m-file.  Any helpful information you put into this first set of
%   comments will displayed.  It is common practice to put a short
%   one-line description into the first help line (also known as the H1
%   line). The one-line descriptions are also used by the
%   LOOKFOR command.
%
%   You may also want to create a Contents.m file in the directory
%   containing your m-files.  This is the Table-Of-Contents mentioned
%   above.
%
%   HELP DIRNAME displays the first set of contiguous comment lines in the
%   Contents.m file.  A typical Contents.m will contain a list of the
%   one-line descriptions of the m-files in that directory grouped
%   together by topic.  In the absence of a Contents.m in the specified
%   directory, MATLAB will create a list of the one-line descriptions for
%   you in directory order.
%
%   For examples look at any m-file or Contents.m file.
