Is it possible to use labCA to retrieve arrays larger than 16K?
Yes - I routinely use that.
You have to make sure EPICS_CA_MAX_ARRAY_BYTES is set
in the environment *before* you start matlab or scilab (RTM).
On the IOC, too, you need EPICS_CA_MAX_ARRAY_BYTES but
since you tested with caget that's obviously set up correctly.

I have EPICS_CA_MAX_ARRAY_BYTES set to a large number and verified
that caget will retrieve a large array but labCA 3.1 returns an error.
data= lcaGet('IBLEMS01_data', 120000);
