MATLAB: Execute script from command line to existing MATLAB instance

command lineMATLABscript

I know I can execute a script from my OS command line with matlab -r "my_file", eventually using -nodesktop to have the output printed in the same window. The problem is that this operation creates a new MATLAB instance to execute the script.

My question is: is it possible to have the script executed in an already open MATLAB instance?

"is it possible to have the script executed in an already open MATLAB instance?"

No.

In some cases needs related to this can be met by using the MATLAB API; see https://www.mathworks.com/help/matlab/programming-interfaces-for-external-languages.html

MATLAB: Have Matlab run in Background from command line

You can look for existing instance of MATLAB and use it for running the new code. I would do something like this [python].

import win32com.client 
oMatlabInstance = win32com.client.GetActiveObject("matlab.Application.7.13")#Checking if MATLAB R2011B is running
oMatlabInstance.execute(new script name here)
