How to import a 3D Python numpy array into Matlab ?

Hello,
I am new to MATLAB as it appears as though Python does not allow to represent four-dimensional data as shown here: https://fr.mathworks.com/help/matlab/visualize/visualizing-four-dimensional-data.html
I have a (10,20,20) numpy array on Python (each value T[x,y,z] is the temperature value of a volume.

(Basically slices of data that look like this)
How can I:
- Export this array to a MATLAB compatible format
- Import it into MATLAB
- And visualize it as shown below:

Thank you in advance for your answer,

The python library Darr allows you to save your Python numpy arrays in a self-documenting and widely readable format, consisting of just binary and text files. When saving your array, it will include code to read that array in a variety of languages, including Matlab. So in essence, it is just one line to save your 4-d array to disk in Python, and then copy-paste the code from the README.txt to load it into Matlab.

In latest R2021a, you can pass a python numpy ndarray to double() and it will convert to a native matlab matrix, even when calling in console the numpy array it will suggest at the bottom "Use double function to convert to a MATLAB array"
