Thats what PyErr_Print() prints.
Python is initialised, for sure

why does it work in C and not in C started within Matlab?

Something like that. Call PyErr_Print() do display the full traceback
so you can find out what the actual problem is.

You've called Py_Initialize() before you do anything else with Py*
functions, right?
