why my Matlab calculate a simple code so solw?

my laptop is Alienware m15 which has qualified configuration for Matlab. But after i install it, i tried a simple code such as "1+1", it ran 4min before giving the answer. I can't figure out what is wrong. Or is it a normal situation?

Which operating system and Matlab version are you using?

On my very old home computer:

tic
two = 1 + 1
toc

Elapsed time is 0.000223 seconds.

Are you sure there weren't some background tasks running (control-shift-esc in Windows to see them) and that MATLAB was fully launched (like it was sitting idle for a minute or two)?

is your current working dir a network location? i have noticed some slow down (though not that extreme) when i'm working from a network location, even when the operations don't involve any file i/o.

When you use this command:

two = 1 + 1

The program should display the results and it takes time to transfer data to graphic cards.

Morever, for timinh, it is better to do the operation for many time (1000 or more) and take the average.

change the code to this:

tic;two=1+1;toc

or in a loop

tic;
for i=1:1000;
    two=1+1;
end;
toc
