Matlab crashes on calllib

Hello,

I am running a code of Dynamxel Motor. It uses built-in libraries of C created by the manufacturers (so i might not read or modify them) located here. When I execute the following, the Matlab exits all of a sudden with no error, or warning:

VALUE = calllib(lib_name, 'portHandler', DEVICE_NAME)

Will appreciate any help, thanks alot..

Have you solve the issue ? i also meet with this problem when calling Nimotion's Nim_init(const char* strSdkPath) function, it just crashes repeatedly. Why does MATLAB crash when I make a function call on a DLL in MATLAB 7.6 (R2008a)? - MATLAB Answers - MATLAB Central (mathworks.com) does not work for this issue
