Rob,
We *should* be able to figure something out for you. I'm fairly
certain the GetFullMatrix method returns a SAFEARRAY which is not
supported by the IDL 5.5 COM bridge - SAFEARRAY majority is the
opposite of IDL's storage.
I'd suggest we try using the MATLAB Engine which is a lower level C
API. Please contact me directly to discuss in more detail and then we
can share our findings with the group once we have tried a few things.
Thanks,
-Paul
