How can transfer python result to Matlab matrix

I use 'system' to import a python coding and got the result as show below:

G= 

  Python ndarray with properties:

           T: [1×1 py.numpy.ndarray]
        base: [1×1 py.NoneType]
      ctypes: [1×1 py.numpy.core._internal._ctypes]
        data: [1×3 py.memoryview]
       dtype: [1×1 py.numpy.dtype]
       flags: [1×1 py.numpy.flagsobj]
        flat: [1×1 py.numpy.flatiter]
        imag: [1×1 py.numpy.ndarray]
    itemsize: [1×1 py.int]
      nbytes: [1×1 py.int]
        ndim: [1×1 py.int]
        real: [1×1 py.numpy.ndarray]
       shape: [1×2 py.tuple]
        size: [1×1 py.int]
     strides: [1×2 py.tuple]

    [[1.00000001  1.00000001  3.00000001]
     [1.00000001  1.00000001  3.00000001]
     [1.00000001  1.00000001  3.00000001]]
 

How Can I transfer the data of G in format of Matlab matrix ?

I have solved this question in general case. Thank you!

You need to save this array in a format that MATLAB understands. You could use scipy.io to do this.

As an example:

import numpy as np
import scipy.io

x = np.linspace(0, 2 * np.pi, 100)
y = np.cos(x)

scipy.io.savemat('test.mat', dict(x=x, y=y))

You can then load this in matlab with "load". Refer to the following for more information:

"load" command in MATLAB - https://www.mathworks.com/help/matlab/ref/load.html

"scipy.io.savemat" - https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.savemat.html

Thank you Agnish, I have found a way to transfer directly in matlab.

May you please inform about the way you transfer the results directly to matlab?

I'm having the same problem.

For example, In Matlab

A_Array=py.numpy.array(B) % B is the data which you got from python, A is in array format
A_matrix=nparray2mat(A_Array); %change python array to matlab matrix

you can find nparray2mat in this answer:
