Hello there everybody,
I would like to ask for help. I am a developer in a company that's client of your solution. I am in charge of developing a call to exported DLLs from Matlab and am actually doing the technical/functional analyses of this demand. We have licensed MATLAB 2013 and i asked the user to export the DLL in all the option he has available. As of my first "hello world" kind of test, i picked this DLL as C exported type, which is a calculating function they have in here. Runtime is installed, same version and architecture (32 bit).
I am executing mclmcrInitialize first. Then mclInitializeApplication. Further, if no errors, i am executing the DLL initialize function and executing the calculation function. After that i am terminating the DLL.
But i am getting this dump as follows. Could anybody please help me figure out what this stack means?
Much appreciated,
