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

In python sqrt always returned as float.Try sqrt(4.0)
