open an application .exe file in matlab if the application is not already running on the pc in matlab

To open an .exe file in MATLAB, you can use the system function. However, please note that MATLAB itself cannot directly execute .exe files. Instead, you can use the system function to run the .exe file from the command prompt.

Here is an example of how you can open an .exe file in MATLAB:

main.m
filename = 'C:\path\to\file.exe';
system(filename);
52 chars
3 lines

Replace "C:\path\to\file.exe" with the path to your .exe file.

Please note that the .exe file should be executable from the command line and not rely on any external tools or dependencies that might not be available on the system where MATLAB is running. Additionally, keep in mind that MATLAB will not display the application's graphical user interface (GUI) - it will be launched in a separate window.

If the application is not already running on the PC, running the .exe file using system should start it for you.
