This message is mostly relevant for those who like to use a current
gretl snapshot, or build gretl from the git sources -- and in
particular for anyone who's using the function packages cmatrix or
ghosts.
A big set of changes has just landed in git and snapshots, providing
native complex matrix support for gretl. The new functionality is
described in
http://gretl.sourceforge.net/complex_matrices.pdf
(A version of this will make its way into the Gretl User's Guide in
due course.)
To the best of our knowledge these changes will not break anything
apart from the cmatrix and ghosts packages. Cmatrix will no longer be
needed, since the functionality it provided is now built in, and
there's a new version of ghosts (multivariate spectra) available that
uses the new complex apparatus. The prior version of ghosts (0.3) will
not be replaced in the main listing of packages until the next gretl
release, but you can install the update via the following command in
the gretl console:
pkg install \
http://ricardo.ecn.wfu.edu/gretl/staging_fnfiles/ghosts.zip
Note that the update (version 1.0) requires git or a snapshot from
today (August 27) or later.
