It sounds like a currupt Matlab installation. I would suggest you reinstall Matlab and if the problem still persists, call the Mathworks support.

Yeah, I have reinstalled it, and the problem still there, I give it up, it spent much time till now, I have to! Still thank you very much
Try restoring Matlab's search path to the default. You may have duplicate functions that are shadowing Matlab's internal functions. If the problem still persists, you should be eligible for free telephone support.
