restoredefaultpath;matlabrc

[rockybalboa]

Hi, I have the following error when I start matlab (please see below). I tried to uninstall matlab and reinstall it again but I still have the same problem.
Any help is greatly appreciated.

I had this same problem and fixed it through modifying the pathdef.m file. You can view it by typing "open pathdef" in the command window. The displayed faulty form was as shown below:

function p = pathdef
%PATHDEF Search path defaults.
% PATHDEF returns a string that can be used as input to MATLABPATH
% in order to set the path.

p = [...
%%% BEGIN ENTRIES %%%
'C:\Users\"username"\Documents\MATLAB;', ...
c:\program files (x86)\matlab\r2007a student\toolbox\matlab\general;', ...
c:\program files (x86)\matlab\r2007a student\toolbox\matlab\ops;', ...
c:\program files (x86)\matlab\r2007a student\toolbox\matlab\lang;', ...
c:\program files (x86)\matlab\r2007a student\toolbox\matlab\elmat;', ...

I changed this to the following form and it made everything work correctly... or at least so it seems to this point.

p = [...
%%% BEGIN ENTRIES %%%
'C:\Users\"username"\Documents\MATLAB;', ...
matlabroot,'\toolbox\matlab\general;', ...
matlabroot,'\toolbox\matlab\ops;', ...
matlabroot,'\toolbox\matlab\lang;', ...
matlabroot,'\toolbox\matlab\elmat;', ...

Hope this helps...

I am having the same problem.
When I opened pathdef.m file, it was empty!!
