[Gretl-users] New complex matrix support

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. -- Allin Cottrell Department of Economics Wake Forest University, NC
