How to run multiple cores without graphical interfaces?
Usually, I use the graphical interface of MATLAB to execute the following code.
an example,
parpool('local',4);
parfor ik=1:10
a(ik)=1;
end
But this code can not be run if I don't open the graphical interface of MATLAB.
I would like to know how to run a programe like this example without the graphical interface of MATLAB.
Can I implement the calculation with other commands without the graphical interface of MATLAB?

The problem might be hidden in te expression "can not be run if I don't open the graphical interface". What are you doing exactly? To understand what happens, it is helpful if you post, what you are doing and what you observe. E.g. do you get an error message?

Thanks for your help. I know what happened now. I use '-nojvm' to run matlab which does not allow parpool to work according to Edric Ellis's answer. When I use '-nodisplay', everything works well.

I'm guessing you're starting MATLAB by running matlab -nojvm. This will not allow parpool to work. Use matlab -nodisplay instead.
