Hello,
I installed the Python engine module as
On Mac or Linux systems:
cd "matlabroot/extern/engines/python"
python setup.py install
No error message. But when I try the example:
import matlab.engine
eng = matlab.engine.start_matlab()
print(eng.sqrt(4))
I get:
EngineError: Import argument 'matlab.internal.engine.input' cannot be found or cannot be imported.
No clue what is going on. Shouldn't this be tested at the installation time? I appreciate any comments.
Thanks, -fernando
