How do i run a matlab file in python?
Hi, Show
this is not a big deal. The python code looks like: import matlab.engine eng = matlab.engine.start_matlab() eng.simple_script(nargout=0) eng.quit() The Matlab script would be perhaps this one line saved as simple_script.m: Make sure that the script is saved in a folder matlab knows as a search folder. Then run your python script and get the answer: It is not necessary that you have a function in your .m-file, but possible. See more information here. The Matlab screen is not visible by default, so you should be happy if you follow this and the linked information... Best regards Stephan Main Content This example shows how to call a MATLAB® script to compute the area of a triangle from Python®. To call a MATLAB script or function, put it on your MATLAB path. For this example, create a MATLAB script in a file named b = 5; h = 3; a = 0.5*(b.* h) After you save the file, start Python and call the script. import matlab.engine eng = matlab.engine.start_matlab() eng.triarea(nargout=0) Specify Convert the script to a function and call the function from the engine. To edit the file, open the MATLAB editor. eng.edit('triarea',nargout=0) Delete the three statements. Then add a function declaration and save the file. function a = triarea(b,h)
a = 0.5*(b.* h); Call the new ret = eng.triarea(1.0,5.0) print(ret) The See Also
