I have the Distributed Computing Toolbox which I am using with the builtin 'local' 12 worker profile.
How can I set LD_LIBRARY_PATH for those workers?

I think I found a solution.
I copied .matlab7rc.sh from MATLABROOT to my home directory, and edited to add the directory I need in LD_LIBRARY_PATH to the LDPATH_SUFFIX variable.
The copy in the home dir seems to override the one in MATLABROOT and this seems to effect the workers as well as a normal Matlab session.

Use below sequence of commands to set LD_LIBRARY_PATH for 12 workers:
parpool(12);
pctRunOnAll setenv('LD_LIBRARY_PATH',getenv('PATH'));
getenv('LD_LIBRARY_PATH');
delete(gcp);
You require parallel computing toolbox to be installed on your machine. I tested this on MATLAB R2014a to be working as expected.

I don't think this will work. To have an effect LD_LIBRARY_PATH must be set in the shell environment calling the executable. I don't think setting it post hoc from within the running worker will have any effect.
