out of memory

I'm working in matlab GUI and it occupies more memory and cause out-of-memory error. Even if I clear all the variables by clearvars, the memory remains
 >> memory
Maximum possible array:              11 MB (1.112e+007 bytes) *
Memory available for all arrays:    267 MB (2.799e+008 bytes) **
Memory used by MATLAB:             1477 MB (1.548e+009 bytes)
Physical Memory (RAM):             2766 MB (2.900e+009 bytes)
Could anyone help me how to flush out the memory used by MATLAB???

Best Answer

See pack.
More powerful:
!matlab &
exit
See Answers: How to reset Matlab to its launched state .
But when diskswapping was used intensively even restarting Matlab can leave the operating system in a state of a reduced responsiveness. Then use the most powerful FEX: WinPower:
WinPower('RebootMatlab', 'disp(''Hello again'')');
This restarts the computer...
