I need to call a python function from a Matlab environment. Is it
possible?
Let's assume, I have the following python code:
def squared(x):
y = x * x
return y
I want to call squared(3) from Matlab workspace/code and get 9.
Thanks for your feedback.

You can write a .mex file which calls Python API functions. These should
be, among others,
init:
Py_Initialize()
for providing callbacks or so:
Py_InitModule()
for running:
PyRun_String()
PyRun_SimpleString()
PyImport_Import()
-> PyObject_GetAttrString()
-> PyCallable_Check()
-> PyObject_CallObject()
etc. etc.
at the end:
Py_Finalize()
For details, have a closer look at the API documentation, e. g.
http://docs.python.org/c-api/veryhigh.html.
Additionally, you have to care about conversion of data types between
the MATLAB and Python types. Here you can look at
http://www.mathworks.com/help/techdoc/apiref/bqoqnz0.html
Alternatively, you can call the python libraries using
