Armadillo received a contribution for qz(). I would like to expose this in RcppArmadillo, and can when we have a feature-full LAPACK (eg on Linux or OS X when extern LAPACK is used).
On Windows, and other systems with Rlapack, Armadillo would need
sgges, dgges, cgges, zgges
As with prior practive 's*' and 'c*' are not going to be used by R, but maybe dgges and zgges could be included in time for R 3.3 ?
I could try and help with a patch if you'd want me to.
Sounds reasonable to me.... notably if you provide a patch (against R-devel),
including appropriate changes to
src/modules/lapack/README (needs updating; contains other files to consider)
Also, from more discussion with Conrad and Keith, we'd want
and with that the Subject of the bug report is back in line.
Created attachment 1860 [details]
Update Rlapack to include zgges, zgetri, and zgels
This should add the functionality that Dirk mentioned. Changes were made to
zgges required a total of 13 additional LAPACK routines; zgetri and zgels only needed 3 and 1 additions (resp.).

Is there anything additional we need to provide for this?
