Shut down Matlab and open new Matlab instance

I want to close the current Matlab instance and open the new Matlab instance through Matlab command or script...Any inputs??

Answer 1

[Srinivas]

something like this

Curr_dir = pwd;
bat_str = ['"' matlabroot '\bin\matlab.exe' '"'];

fid = fopen('restart_matlab.bat','w');
fprintf(fid, '%s\n', ['cd ' Curr_dir]);
fprintf(fid, '\n%s', bat_str);
fclose(fid);

system('restart_matlab.bat')
exit

HTH

Thank you Srinivas for the answer. I implemented your suggestion. Its working as per my expectations. But it is creating one .bat (restart_matlab.bat) file. Is it possible to have same functionality without generation of additional files(here, .bat file)..

Once again Thank you for the earlier reply and looking forward for the response

[Srinivas]

just delete the bat file

Curr_dir = pwd;
bat_str = ['"' matlabroot '\bin\matlab.exe' '"'];
fid = fopen('restart_matlab.bat','w');
fprintf(fid, '%s\n', ['cd ' Curr_dir]);
fprintf(fid, '\n%s', bat_str);
fclose(fid);
system('restart_matlab.bat')
delete('restart_matlab.bat')
exit

In a release a couple of years ago, I created a "finish.m" on the path and within the file it was just "matlab".

When closing MATLAB, with would run finish.m and while closing MATLAB it would start another one.

I am sorry but I didnt understand your text.. Could you please elaborate.. Thank you for the earlier reply..an looking forward for the response

[Andreas Goser]

Create a new file called finish.m. Type just the word matlab in it and save.

[Sean de Wolski]

@Andreas, I assume you need to have the '&' after 'matlab' otherwise it will hold closing the first session until the second has closed.

[Andreas Goser]

Maybe... I haven't tried. This is what I did probably 8y ago ;-)

Answer 3

[Sean de Wolski]

system('matlab &');exit

[per isakson]

Warning: Do not put system('matlab &');exit in finish.m !

I did and it put my system into a loop of starting Matlab sessions. It choked the system and it was not possible to delete finish.m with the Windows Explorer. Ctrl+Alt+Del didn't work. Pushing the power button six second made it stop.

    system('matlab &')

does start one new instance of Matlab.

[Sean de Wolski]

I never suggested putting this in finish.m :)

[per isakson]

@Sean, I don't blame you. I tried despite I thought it was wrong.

However, your answer together with your comment on Andreas' answer might make someone misunderstand. Thus, I think a warning is appropriate. This text might be around for years!

Hello @per,

Is there a way to do it on Linux? I tried the above command, it shows the startup screen but does not launch a new window?

Thanks!

system('nohup matlab 2>&1 &')
