Why does Matlab graphics use a lot of memory?

When I draw even the simplest plot in Matlab, each plot takes about 400MB of memory. I tried without re-installation, no effect.

Anyone having a similar problem?

I tried another computer in our office and found that the simplest plot takes about 20MB of memory, which seems like a lot, but it's great.

0.4GB, however, is insane, and plotting more than three graphs makes my computer useless.

I tried:

 plot(1:10,1:10);

      

        
        
        
      

    

or

 plot(1,1);

      

        
        
        
      

    

and similar plot commands.

figure();

itself does not use most of the memory, only graphics.
