[GAP Forum] New linear algebra package, 'linboxing'

Dear GAP forum,

I'd like to announce a new GAP package called 'linboxing' 
(LinBox-in-GAP) that provides an interface between GAP and the LinBox 
exact linear algebra library. At present, the package provides 
alternative versions of Rank, Determinant and SolutionMat which are much 
faster than GAP's native versions when dealing with large matrices over 
the integers or large prime fields.

The package needs the LinBox C++ library to be compiled and installed 
(see http://www.linalg.org/), and provides a compiled GAP kernel module 
that performs the actual interfacing at the kernel-level. It's been 
tested under various versions of Linux and on OS X, but won't work on 
Windows at the moment.

For more information, see the GAP website at
or the linboxing website

If you have any problems with installation, please let me know. I'd 
welcome any feedback, be it reports of observed gains from using the 
package, requests for additional functionality, or any other comments.

Best wishes,
