Running matlab from linux terminal

Hi,

I was wondering whether someone could help me in figuring out why running a matlab script is much much slower when run from a linux terminal as compared to that run from matlab windows itself.

Lets say I have a matlab .m file called frequency.m. This when run from matlab windows itself (I mean the desktop matlab application) takes about 10 minutes to produce the output whereas the same .m file when run from the terminal window using the line of code:

matlab -nodisplay -nosplash -nodesktop -r "run('path_to_my_script/frequency.m) ; exit ; "

takes about 30 minutes to produce the same output.

The path_to_my_script was the path which I found by moving to the directory containing the frequency.m file from my terminal and typing pwd. The path so obtained was inserted into path_to_my_script in the above code.

Is there any reason for this and any solution to make the script run faster from linux terminal?

Thanks.

If you're running it in -nodisplay, then -batch option is for you.Try that.

You mean :

matlab -batch "frequency.m" ?

i can't tell exactly, it's best if you check the documentation, as there are some prerequisites to running the script like that.

Allright. Thank you.
