hi,
 
i have just published a linear algebra library at http://www.johnring.co.uk/downloads.shtml
 
It has the following functionality: Template based C++ classes and routines for linear algebra. Matrix storage types : (dense, packed (tri, sym, herm), banded) all row/col major, compressed diagonal. Vector with STL container type methods. BLAS interface routines.
 
i would be grateful if people could take a look and get back to me with any comments,
 
many thanks,
 
john
