Has anyone used these variable definitions (chapter 10 of the manual)?

init_vector_vector init_matrix_vector

They don't appear to work.

Hi Ian,

Thanks for your questions.

I think a new introductory document is in the works. Mark Schildhauer 
from NCEAS has commissioned something but I haven't seen a copy nor do I

know its status.

We are in the process of simplifying the production of LaTeX 
documentation with a new ADMB style package. Work progressing well and 
the package should be available in January.

If you have useful information to share from you exploration of the 
code, adding comments to the API documentation would be very helpful. 
You can see the draft API documentaion at 
http://admb-project.org/documentation/api/Doxygen/

Finally, the Community pages are intended for contributions from users. 
So anything you feel might be helpful to others would be welcome. These 
pages seem a bit disorganized to me and some are out of date, but they 
are probably useful nevertheless.

Cheers,
John
