I am looking for a concise expression to find eigenvalues in J (for
small matrices)
lapack is not universally available, so I am ignoring it.
Here's the best I have been able to find (loosely based on an "At Play
With J" article)
ev=: 1 {:: [: p.@> [: -&.>/ .(+//.@(*/)&.>) ] <@,"0 -@=@i.@#
Is there some way to eliminate the boxing and unboxing here?
Thanks,
