Error using code straight from wiki?

brandonparsons opened this issue 11 years ago · 8 comments

I'm trying to do the following, straight from the wiki:

array = MDMatrix.fromfunction("double", [4, 4]) { |x, y| x + y }

And getting the following error:

Other functions from MDArray are working, so the installation is (at least partially) correct. I just installed by putting mdarray in my Gemfile.

Brandom,

Seems like you don't have the java classpath ser properly. The best way to
install is by doing jruby -S gem install mdarray.

Please try that first.

Thanks for the quick reply. No way to do this from the gemfile? I like to
automate installation of gems on production machines.

You need to manually set your java classpath then. There is a mdarray.jar
file that needs to be on the classpsth. I'm on vacation, so cannot really
look at my computer.

Hi Brandon,

Where you able to get mdarray working?

I'm back from vacation; if you need any further assistance let me know.

Good luck!

Yeah I think it was an issue with my Java version. I upgraded to 1.7 and it appears to be working now. Thanks for your time 👍

Answer 6 · 2014-01-16T12:21:47.000Z

Great,

I´ll close the issue. If you feel like, I´d love to hear about your
experience and feedback with MDArray. Are you just testing or planning to
go production?

Cheers,

Hi there,

Sorry for the delayed reply.

I'm actually just developing an application right now using MDArray. I do plan to put it into production (eventually). I was mostly drawn to the inclusion of the COLT statistics - it provides a lot of additional functionality over using something like statsample in MRI.

It has seemed pretty rock solid thus far - if I run into any issues I"ll be sure to let you know.

Answer 8 · 2014-02-04T20:37:17.000Z

Hi Brandon,

Thanks a lot for the feedback. I´m glad that you are able to use MDArray
and all of COLT statistics without problem. Hope to see soon your
application working!

Cheers,

Rodrigo
