Issues in using matlab in python

Hello everyone ,

I am trying to solve an optimization problem where the input to the function to be optimized is a 12x1 vector and the output is a matrix of size 6x3.

I tried solving this using fsolve, root solvers from scipy.optimize

but got the following error:

fsolve: there is a mismatch between the input and output shape of the 'func' argument 'f'.Shape should be (12,) but it is (6,3).

but this problem can be easily solved in matlab using fsolve.

So i created a very simplified version of the original problem :

import matlab.engine

eng = matlab.engine.start_matlab()

import numpy as np

func = lambda x: x[0]**2 + x[1]**2 -25

eng.fsolve(func,eng.rand(2,1))



Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "C:\Users\reach\anaconda3\envs\MyEnv\lib\site-packages\matlab\engine\matlabengine.py", line 66, in __call__

out=_stdout, err=_stderr)

TypeError: unsupported Python data type: function

Any suggestion would be of great help.

Thank you.
