How to clear the memory occupied by matlab??

255 views (last 30 days)
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 &
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...

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