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?

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
