Hello, I have a matlab code for the quantitative differential phase contrast imaging and the code is very big and complicated as well. But the problem is the institute where I am working does not allow to use matlab and they have python and LabVIEW, so I would like to convert the matlab code to python or someone knows how to run the matlab code in python then it also be very helpful.
I have attached the main code.
Thank you.

MATLAB provides two-way integration with many programming languages, including Python. The MATLAB Engine API for Python allows you to call MATLAB functions from Python. Similarly, if you have functions and objects in Python, you can call them directly from MATLAB using the Python Interface. Finally, you can build Python packages from MATLAB programs by using MATLAB Compiler SDK™. These packages can be integrated with Python applications and can be shared with desktop users or deployed to web and enterprise systems. To learn more about using MATLAB with Python go here.

You can use numpy framework which contains matlab libraries.
See cheat sheet , I faced similar situation as you but raged with the cheat sheet, good luck!

@Daniel
The original poster of the question used the term "problem", rather than a phrasing such as "great thing", so it was not a "feature" to the original poster.

@Walter Roberson - ChatGPT may be useful to help you understand sarcasm as well :)

...see?
So it's like other forums in that way, especially like YT forums, but there's no obvious indication of that...
But if you've spent most of your formative years posting on forums that support @ replies, you'd just do that by rote and find that it works. I did find it by typing in @ (for another reason) and as you see if you try that, all sorts of user names will pop up.
So it's dangerous to assume that something is or is not a certain way because quite often it's just a matter of your background and your willingness to experiment and do some research on Google. Some people like that about Life and some don't.

When you are in the editor here, the right hand side has a circled question mark with notation HELP . If you click on that you get documentation about the editor, including
https://www.mathworks.com/matlabcentral/help/rtc#mentions_feature
When you type @, a popup displays the community members already in the Q/A thread. As you keep typing, the list expands to include members not in the thread. A mentioned community member receives a notification when the question/answer/comment is posted. Each mention links the post to the community member's user profile.
