Faber is a Matlab conceptual design toolbox developed by Tim Chau. Currently, the code is not hosted in a repository. A copy of the code can be obtained from the directory
/nfs/carv/d1/people/thomas/Faber-stable
with
>> cp -r /nfs/carv/d1/people/thomas/Faber-stable ~/Faber
There is also another version in
/nfs/carv/d1/people/thomas/Faber-climateOptim
that contains additional climate models. However, this is based on an older version of Faber than is in the Faber-stable directory, so may not include some of the main Faber functionality, and I can't vouch for whether it works well in its current state.
Below are links to the manual and a tutorial.
