If I correctly follow the discussion and particularly Jordi's message at
, the patch was closed and all files removed because the code might have
violated The MathWorks' copyright.
If you are interested in implementing this feature, the project is still
open. But please refrain from "consulting" code in .m files included in
Matlab. Reading their public documentation and asking for results in Matlab
of specific examples on the mailing list is OK afaiu.
