I compiled a .cpp file by mex function and it is compiled successfully but when run the code the matlab is crashed and ask me to stop and restart it.
This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.
How can i know the error and any idea to expected where is error?

You have a bug in your C++ code. You need to post your code before we can help you. If the code is too large, try to boil it down to a small example that reproduces the problem and post that.

Here are some instructions on how to troubleshoot MEX-files. [I don't know how much of this is release specific, so if you're using an older release you may want to search for the version of this documentation page in your installation's local documentation.]
