How to clear the memory occupied by matlab??

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???

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...

Hello,

MATLAB doesn't release memory, if you didn't declare the variable as output for the function.

what variable? for what function? Can you be more specific?
