"myfunction.m" is in the current engine directory. I guess that the input A (mxArray) is not recognized by the engine because I saw errors such like "libmx.dll" is not loaded when I tried to debug the code in visual C++. And I am sure I have added libmx.lib and its path to the appropriate place in visual C++. I copied my code to another computer, and it is working now. But it still is not working using the original computer. I am so confused.
