I was thinking I needed the Java arrays for interop. At one step in my
simulation I need to take an FFT of a 2d array, then multiply that
array with another array, and then inverse FFT. Java array operations
in Clojure seem so slow though that it will actually be better to
convert from either a bui
I think you're still missing some type hints. I think there are
varying degrees of reflective code the compiler can emit, and it
doesn't always warn for the intermediate cases.
Do you need to do all this array business for Java interop, or just
because you believe it will give you maximum perform
Thanks, I just tried using the random number generator in Incanter as
a replacement and it shaves another ~100 msec off the runtime of the
function. That's better but still noticeably slower than python.
I also tried applying what I've learned here to writing a function
that adds two arrays which
Yeah, it will the trade off is you lose line item visibility of
failures. I guess eval isn't too bad in this case.

To relate this example to the OP's request for a concurrency example:
The Clojure versions shown below, if they are correct at all, are correct in
the face of concurrency.
The Java version is not generally correct, and cannot be made correct without
switching to Clojure's interfaces and persist
This is in fact guaranteed. Eloquent documentation patch welcome.

FYI I fired up a profiler and more than 2/3 of the runtime of gaussian-

The Bay Area Clojure User Group had its 25th meeting last night:
http://www.meetup.com/The-Bay-Area-Clojure-User-Group/
It was a great meeting - with Rich talking about the new primitives
stuff in master / 1.3 and explaining design decisions behind the
language! Awesome stuff!
Big thanx to Amit
I'm trying to pass a vector to are, because I need to reuse some
source data. Is there a better way to do this? I don't like the
eval.

I wanted to use insert-values to re-insert the same values to the

I think using "update-or-insert-values" suffices.

The Amsterdam Clojurians meet the 2nd Wednesday of every month in the
center of Amsterdam. We organize on a google group here:

In the last year we've grown from 3 to 33 people, and the growth rate
seems to be accelerating :-)

I have a project called Clodiuno which allows you to control an
Arduino board using either serial or TCP/IP protocol, that may give
you a head start,

One thing that would simplify the process a little is that, when
