How to completely reset Matlab's workspace?

How can I reset Matlab's workspace (environment) as if I restarted it without actually restarting it (to avoid overhead)? Perhaps specifically to trigger garbage collection?
This is in order to resolve the problem of Matlab degrading and become slower over time, probably due to poor memory management:

clear all
will also remove functions and classes from the cache which may further help to trigger garbage collection (for class objects). It may not though.

I'm coming back for more.
I'm using parallel processing to analyze many images at once. If I run the code once, everything is fine, but as soon as I run it a second time, I get an error saying 'Out of memory'. This is annoying because technically I have to exit and restart MatLab every time. Moreover, the updated solution Mr. Robertson has provided doesn't seem to work for me. Please also note that I boosted my laptop's RAM to 32Go, 3200MHz (up from 8Go, 2667MHz) expressively for the purpose of running parallel processing.
This means I need to reconnect to multiple workers (one for each physical core I want to use) every time I need to restart the code. Granted, it's still WAAAAAAAAAY faster than analyzing sequentially (which, for me, took more than an hour for five measly images, compared to about 7 minutes for 5 cores) but still it feels unpolished. Any solution to that would be greatly appreciated!
Thanks in advance! :)
