How about changing the name of the complex-number function to, ideally,
complex?
complex-number seems irritating to (have to) read. Further, calling this
function is a form of type coercion. (float ...), (int ...), etc., are
idiomatic Clojure, whereas (float-number ...), (int-number ...),
That sounds pretty solid imo.

I think the right strategy is to make a separate complex array
implementation library (core.matrix.complex?). In terms of dependencies,
it would only need to depend depend upon core.matrix and complex.
The array representation could simply be a deftype which uses two
underlying arrays for the

Oh man; that is flipping brilliant. And simple...
The implementation should be fairly straightforward, but if anyone wants

Okay. Fixed.

Are these operations (*, +, etc) interoperable with core.matrix operations?
That may end up being pretty key for a lot of numerical users.

Hello Everybody,
I see that Konrad-Hinsen's complex-library in the contrib is a very good
fit.. But I am afraid about the performance since the basic operations are
being dispatched using multi-methods... Does anybody have any say on this?

Thanks David .. but is there a protocol that contains +,*,/,- operations? If
there is one I can simply add those operations...

It's not a protocol, but you may want to take a look at
clojure.contrib.generic.arithmetic for inspiration.
I wish you luck in your complex number implementation! I've done my
own using clojure.contrib.generic and can post if it anyone's
interested.
