How to run matlab code in the server background?

Take the following matlab code for an example. How to run it in the server background? I tried nohup test.m & but failed.

% test.m
A = [
    1,2,3;
    4,5,6;
    7,8,9
    ];
b = [1;1;1];
x = A*b;
save x;

Any suggestion is appreciated. Thanks!

Hi Jingyu Liu,

I understand that you want to run the MATLAB code in the background. One workaround is to utilize MATLAB in command-line mode.

Here are the steps to access MATLAB in this mode:

• Commence MATLAB in command-line mode by entering the following command in the terminal:

matlab -nodesktop       

• This initiates MATLAB without the graphical user interface (GUI).
• With MATLAB running in command-line mode, you can execute your MATLAB code by typing commands or running a MATLAB script or function.To run a script, such as "test.m," simply enter the script's name and press enter. It is possible to access multiple "MATLAB command windows" concurrently.

To Execute a MATLAB script with "nohup" feature, first, open a terminal on your Linux machine. second, navigate to the directory where MATLAB script file is located and execute the below command in the terminal:

nohup matlab -nodisplay -nosplash -r    "run('test.m'); exit" > output.log 2>&1 & 

You can refer to below blog to know more about '-nodesktop' feature:

You can refer to below MATLAB answer to know more about “nohup” feature:

Hope this helps!

I have used "nohup matlab" with different suggested ways that I found in the internet, but I get this error all the time:

nohup: matlab: No such file or directory

while both matlab and nohup are accessible.

Hello, when I run this, I get the following message:

[1] 69286

What does that mean?
