python from matlab in matlab

To call a Python function from MATLAB, you can use the built-in MATLAB function py. Here's an example of how to do it:

1. Install the MATLAB Engine API for Python by following the instructions provided by MathWorks.

2. Create a Python function that you want to call from MATLAB. Save the function in a file, for example, "my_python_function.py". Here's an example of a simple function that adds two numbers:

   main.py
   def add_numbers(a, b):
       return a + b
   40 chars
   3 lines

3. In MATLAB, use the py function to import the Python module and call the function:

   main.m
   % Import the Python module
   py_import = py.importlib.import_module('my_python_function');
   
   % Call the Python function
   result = py.py_import.add_numbers(5, 3);
   
   % Convert the result to a MATLAB variable
   result = double(result);
   226 chars
   9 lines

   In the above example, we import the Python module my_python_function using py.importlib.import_module. Then, we call the Python function add_numbers using py.py_import.add_numbers. The result is then converted to a MATLAB variable using double.

Note: You may need to update your PYTHONPATH environment variable to include the directory where your Python module is located.

Make sure to replace "my_python_function" with the name of your Python module, and "add_numbers" with the name of your Python function.

By using the py function and MATLAB Engine API for Python, you can easily call Python functions from MATLAB.
