<br><font size=2 face="sans-serif">I fixed the bug, it was not in Kronecker
multiplication but in Schur's Complement method, which I had originally
used for</font>
<br><font size=2 face="sans-serif">the LU Decomposition but later implemented
a faster algorithm (from Cormen's MIT book on algorithms).</font>
<br><font size=2 face="sans-serif">The code works now (version 27), but
it needs cleaning.</font>
<br><font size=2 face="sans-serif">It also needs faster normal multiplication
algorithm, cholesky decomp,, eigenvalue finding and a few other basic things.</font>
<br><font size=2 face="sans-serif">I released the code as MIT, and it is
accesible through squeaksource now that it is up again.</font>
