'bindistMT'은(는) 인식할 수 없는 함수 또는 변수입니다.

Caught "std::exception" Exception message is:

Invalid character code sequence detected.

Hi,

I see that you are trying to call and run bindistMT function from command window which is leading to error "'bindistMT'은(는) 인식할 수 없는 함수 또는 변수입니다" because You are trying to call the function which is not defined yet and however Function definition are not supported in command window.Hence we suggest you to save the above code by creating a new script .

And regarding the "Invalid character code sequence detected."

"Invalid character code sequence detected." usually means non-English characters in path or file name. Some potential path:

>> tempdir

>> prefdir

>> matlabroot

>> !hostname

In this case, !hostname contains non english characters. Change it to pure English and it will work

Hope it helps.
