Hello,
I am trying to do some operations inside a parallel section sequentially.
In every parallel framework that I have worked with, there is something like mutexes, semaphores, critical etc which allow you to do this.
Matlab lacks this features and a relevant submission that I found in the file exchange, which was also suggested by a mathworks engineer in another question, was full of persistent variables which could possibly lead to bugs.
Any ideas?
thanks

spmd has some tools for this. See labbarrier and the lab send and receive functions.
Unfortunately mutexes over networks are difficult. See e.g., the discussion http://www.mathworks.com/matlabcentral/newsreader/view_thread/279510
