pack Consolidate workspace memory.
pack performs memory garbage collection. Extended MATLAB sessions may cause memory to become fragmented, preventing
large variables from being stored. pack is a command that saves all variables on disk, clears the memory, and then
reloads the variables.
If you run out of memory often, here are some additional system
Windows: Increase virtual memory using the control panel.
Unix: Ask your system manager to increase your Swap Space.
You should cd to a directory where you have “write” permission to execute this command successfully. The following lines of code will help you accomplish the consolidation of workspace memory.
cwd = pwd; cd(tempdir); pack cd(cwd)
