Answer 3

[Hadi Khabbaz]

Thanks a bundle Mr Walter Roberson. In command window I typed: restoredefaultpath; rehash toolboxcache; It worked perfectly. However, if I close MATLAB and open it again, the same problem will come back.

[Walter Roberson]

Go into pathtool and save your path.

Thanks a lot Mr Walter Roberson. The same problem occurs to me, but after saving my path, I close MATLAB and open it again, the problem happens no more.
