在 MATLAB Online 中打开

I can reproduce your error message with following steps:

>>> import matlab.engine
>>> eng=matlab.engine.start_matlab("-nojvm")
>>> eng.sqrt
<matlab.engine.matlabengine.MatlabFunc object at 0x7f4efd26ded0>

If that is what you did, the simple fix is to provide arguments for the function call like this:

>>> eng.sqrt(4.)

I modified the script and finally i've fixed the error. This is my code:

import matlab.engine

eng=matlab.engine.start_matlab()

eng.cd(r'C:\Users\Alejandro\Desktop',nargout=0)

eng.run('Test',nargout=0)

I used the command 'run' in order to execute the script

i would appreciate if you could answer to me another question. I want to run a Matlab script from python using the engine and at the same time this script will need variables defined in the python script, There is any way to do that?
