After installing R2014b, help and doc commands no longer work correctly. Is there a fix? Some background:
  • help followed by any function name returns a fileparts error (example below)
  • doc sometimes crashes Matlab, sometimes results in an error (example below), and sometimes opens up a help window as expected
help clear % Trying to display command window help for "clear" function
Error using fileparts
Too many output arguments.
Error in makehelphyper (line 73)
[unused fcnName unused unused] = fileparts(fcnName);
Error in help>displayHelp (line 211)
helpStr = makehelphyper('help', pathname, JRI_linkableTopic,
helpStr);
Error in help (line 130)
displayHelp(helpStr, topic, usejava('desktop'));
doc quantile % Trying to open standalone help window for "quantile" function
Too many output arguments.
Error in help (line 138)
[varargout{1:nargout}] = [helpStr moreInfo];
Error in help2xml (line 48)
[helpstr, docTopic] = help(topic, helpCommandOption);
Error in help2html (line 20)
[helpNode, helpstr, fcnName, found] = help2xml(dom, topic, pagetitle,
helpCommandOption);
Error in helpwin (line 76)
html = help2html(topic,pagetitle,helpCommandOption);
Error in doc>showHelpwin (line 221)
foundTopic = helpwin(topic, '', '', '-doc');
Error in doc (line 112)
if ~showHelpwin(topic)
138 [varargout{1:nargout}] = [helpStr moreInfo];

Only this, C:\Program Files\MATLAB\R2014b\toolbox\matlab\iofun\fileparts.m

It looks like it's using a help command from an earlier release (fileparts does not currently support four outputs)
Try refreshing the path
restoredefaultpath
rehash toolboxcache
If it works after that;
savepath

[If someone is thinking of trying this solution, I suggest copying pathdef.m to a temporary file first, so you can restore your personal path directories afterward.]
