If I start a pool using "pmode start local 4" then try to connect to that pool via "p = gcp" I get p.NumWorkers = 0. But in the lower left corner it tells me the Number of workers is 4. How many workers do I have???

There's a difference between pmode and parpool. Behind the scenes, they both share some functionality, and there's some ... unintended behaviour going on here. gcp is intended to work only with parpool, and not pmode. If you don't want to use the PMODE window, I suggest using instead
parpool('local', 4)
Right now, it doesn't work to mix pmode and parpool-type functionality.

Unfortunately when I do "parpool('local',4)" Matlab ignores my breakpoints so that I can't debug my parallel code.
