Hi
I'm trying to install python on Matlab2014b to call some Matlab script from Python. I add the Python path in Matlab and write the following command:
cd "matlabroot\extern\engines\python"
python setup.py install
(where matlabroot is the path where Matlab is installed) but I get the following error:
"Undefined function 'python' for input arguments of type 'char'"
I controlled and in the current folder the file"setup.py" exists. Where I am wrong?
thanks

You are supposed to run the command from the system prompt, not MATLAB command window:
"To install the engine API, execute the following commands at the operating system prompt, where matlabroot is the path to the MATLAB folder."

Assuming that you're trying to execute the python command this won't work:
cd "matlabroot\extern\engines\python"
python setup.py install
because it's trying to interpret the python "word" as a valid MATLAB function or variable.
You may have more luck with the bang command.
