Re: [ojAlgo-user] Complex SVD

[Bayard F. <bf...@gm...>]

How do I access the Java_5_6 branch?  If I try
cvs -z3 -d:pserver:ano...@oj...:/cvsroot/ojalgo co
-Pr Java_5_6 DevProj
I get "no such tag Java_5_6".  Apologies, I don't use CVS much.

I got it to compile with Java 7 on Mac and it is much faster, only 6 to 20
times slower with ComplexNumber compared to Double.

However I still need a Java 6 version on Mac due to lack of support from
Oracle.

Thanks,
Bayard
