Implement sparse * diagonal and diagonal * sparse operations, double-prec only. Date: Sun, 8 Mar 2009 16:28:18 -0400 These preserve sparsity, so eye(5) * sprand (5, 5, .2) is *sparse* and not dense. This may affect people who use multiplication by eye() rather than full(). The liboctave routines do *not* check if arguments are scalars in disguise. There is a type problem with checking at that level. I suspect we want diag * "sparse scalar" to stay diagonal, but we have to return a sparse matrix at the liboctave. Rather than worrying about that in liboctave, we cope with it when binding to Octave and return the correct higher-level type. The implementation is in Sparse-diag-op-defs.h rather than Sparse-op-defs.h to limit recompilation. And the implementations are templates rather than macros to produce better compiler errors and debugging information.

Things to do before making a release:

  * Ask testers for the type(s) of machines they are using.

  * Update the version number in src/version.h.

  * Update the version number in doc/refcard.tex.

  * Add a `Version M.N.P released.' line to the ChangeLog.

  * Update the NEWS file.

  * Check the README file.

  * Create a new Announce.M.N.P file for the current release.

  * Run autoconf, autoheader, and configure before making tar files.

  * Update the NEWS and README.octave files in the anonymous ftp
    directory.
