The answer is related to your splicing questions. What gets passed to the
macro is not the value of the argument, but rather the symbolic expression
of the argument. If I didn't use a temporary variable, that symbolic

This is what I came up with for the full matrix calculation:

I now have a macro for the elements of M, another for the elements of Q and
yet another for the elements of L. In the end I define the genmatL function

On a more general note, I am thinking that with a bit of cleanup, this code

Hi all,
I used KyotoCabinet http://fallabs.com/kyotocabinet/ key-value storage in
some of my Python projects, but couldn't find bindings for Julia. So I
wrote something by myself. Hope it might be useful for someone else.

any reason you are using homebrew to install julia? both the build and
precompiled binary are straightforward to install, I would go with that.

Could you file this as an issue? Which version of Julia are you using and

This sounds like you have an old version of gcc installed and need to

Thanks for announcing this! I have used other key value stores on

now.
With a quick look, you code seems really clean. The only thing that caught

Cool! I've used KyotoCabinet before, so it's nice to see this coming in to

Hi Elliot,
Just to clarify, the KyotoCabinet license is actually GPLv3, with the
option to purchase a separate commercial license. (One has to download the
source to actually see the license.) But I agree that it's a good idea to
clarify the license situation.
Cheers,

Ah, I see, as long as your application is opensource and is licensed under
one of the licenses they list, (BSD is listed there, so I imagine MIT is
acceptable to them) you don't have to buy a commercial license. Good to
know.

Thanks for your response. No particular reason but I tend to use home-brew
for most things as it sometimes gives flexibility when you need multiple
compiler versions. I would have tried the pre-compiled binary next.

Just curious where you saw BSD listed--I couldn't find it anywhere.
If you download the tar ball (
