Can you post the complete error in case it is different to the one below?

Warning: Executing startup failed in matlabrc. This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was: MATLAB:load:couldNotReadFile Unable to read file 'matlab.mat': no such file or directory. > In matlabrc at 191

Moreover, another error was shown if I executed "load" comment,

Error using load Unable to read file 'matlab.mat': no such file or directory.

Do you have a sartup.m file somewhere and if yes, what is in it?

That is the currently repeatable error.

Here is my 'startup.m':

function startup

% Parameters that can be set in text file (config.txt)
%
% Nsites
% ResultFile
% SnapshotDir
% CalibrationFile
% DisplayWarnings
% Teams: List of teams separated by a comma
% 

fid = fopen('config.txt','r');
if (fid > 0)

      data = textscan(fid,'%s%s', 'Delimiter', '=', 'CommentStyle', '#');
      data = [data{:}]';    
      fclose(fid);

      data(:,cellfun(@isempty, data(2,:))) = [];

      if any(strcmpi(data(1,:),'Teams'))
          data(2,strcmpi(data(1,:),'Teams')) = ...
              textscan(data{2,strcmpi(data(1,:),'Teams')},'%s','Delimiter',',');        
      end

else

      data = {};

end

judge_control(data{:})

I'm on Mac running the latest versions of:

OS X El Capitan (10.11.3); XCode (7.2), and Java 8 Update 71 (build 1.8.0_71-b15).

That startup.m appears to be left over from the Mars Rover Competition or similar. Remove it or rename it.
