Subject: Re: how to solve a special JRuby and Java syntax conflict?

Dear Paul, Walton, Matthew, Mario and Colin,

thank you for your very helpful and detailed responses.
I also posted on the JRuby mailing list, and like you
told me, the line

java_arr = ruby_arr.to_java Java::double[]

can solve my problem.
I am actually trying to use jmatharray for
singular value decompositions of matrices (http://en.wikipedia.org/wiki/Singular_value_decomposition).
Mario, your examples were very enlightening for understanding the communication between JRuby and Java. I had so far managed to use either
one of Ruby and Java, but not both together :)
Colin, your code also looks very interesting. So far, I am quite happy that
I actually can use JRuby and jmatharray together for solving the immediate
problem at hand.

Thank you very much!

Best regards,

Axel
