Description of m2html

0001 function m2html(varargin)
0002 %M2HTML - Documentation System for Matlab M-files in HTML
0003 %  M2HTML by itself generates an HTML documentation of Matlab M-files in the
0004 %  current directory. HTML files are also written in the current directory.
0005 %  M2HTML('PropertyName1',PropertyValue1,'PropertyName2',PropertyValue2,...)
0006 %  sets multiple option values. The list of option names and default values is:
0007 %    o mFiles - Cell array of strings or character array containing the
0008 %       list of M-files and/or directories of M-files for which an HTML
0009 %       documentation will be built [ '.' ]
0010 %    o htmlDir - Top level directory for generated HTML files [ '.' ]
0011 %    o recursive - Process subdirectories [ on | {off} ]
0012 %    o source - Include Matlab source code in the HTML documentation
0013 %                               [ {on} | off ]
0014 %    o syntaxHighlighting - Syntax Highlighting [ {on} | off ]
0015 %    o tabs - Replace '\t' (horizontal tab) in source code by n white space
0016 %        characters [ 0 ... {4} ... n ]
0017 %    o globalHypertextLinks - Hypertext links among separate Matlab
0018 %        directories [ on | {off} ]
0019 %    o todo - Create a TODO file in each directory summarizing all the
0020 %        '% TODO %' lines found in Matlab code [ on | {off}]
0021 %    o graph - Compute a dependency graph using GraphViz [ on | {off}]
0022 %        'dot' required, see <http://www.research.att.com/sw/tools/graphviz/>
0023 %    o indexFile - Basename of the HTML index file [ 'index' ]
0024 %    o extension - Extension of generated HTML files [ '.html' ]
0025 %    o template - HTML template name to use [ 'blue' ]
0026 %    o save - Save current state after M-files parsing in 'm2html.mat'
0027 %        in directory htmlDir [ on | {off}]
0028 %    o load - Load a previously saved '.mat' M2HTML state to generate HTML
0029 %        files once again with possibly other options [ <none> ]
0030 %    o verbose - Verbose mode [ {on} | off ]
0031 %
0032 %  Examples:
0033 %    >> m2html('mfiles','matlab', 'htmldir','doc');
0034 %    >> m2html('mfiles',{'matlab/signal' 'matlab/image'}, 'htmldir','doc');
0035 %    >> m2html('mfiles','matlab', 'htmldir','doc', 'recursive','on');
0036 %    >> m2html('mfiles','mytoolbox', 'htmldir','doc', 'source','off');
0037 %    >> m2html('mfiles','matlab', 'htmldir','doc', 'global','on');
0038 %    >> m2html( ... , 'template','frame', 'index','menu');
