Trying to use Apache Commons Math

edited May 2018 in Library Questions

I'm trying to import math's DBScan from apache commons, but I have no idea if it's even possible to do this with Processing. If so, could someone please help me out?


  • If you got its ".jar" file, you can simply drag it into the Processing's IDE (PDE).

  • Thanks GoToLoop - and if I just have a bunch of .java files? I saw a similar question posted before, but the OP answered their own question, and didn't go to length explaining the process ( Any help would be appreciated!

    If they're ".java" files, you can simply copy & paste them into the same folder as your ".pde" files. :bz

    Take a look at the sketch from these links below. They're for the same sketch btW: O:-)


    That sketch is made of 1 ".pde" file: "CountdownClass.pde"
    And a ".java" 1: ""

  • Thanks GoToLoop! That's very helpful in explaining things - I think I get it now. I've been using Processing for simple graphics for a bit, but this is another level of complexity.

    If you don't mind, given that JSAT is some 500+ files java files, is there any way to import all of them en masse? Do I need to drag in all the files into my Processing sketch?(!)

    That seems a huge complex collection of libraries. @-)
    You really need to find its distribution ".jar" file on its own site. #:-S
    Or try out Maven:|ga|1|a:"JSAT" [-O<

  • Thanks for the reference to search.maven Instead of dealing with JSAT, I figured I should type DBSCAN to see if anything came up, because that's all I'm after for now. I got two results (webjars and weka). These seem less complicated than JSAT (at least I got the .jar files!), but I'm still not sure how to use them. I've imported them into my sketch (by copying the .jar files into modes/java/libraries/..., but not sure where to go from there. :-?

    GoToLoop, do you think you can point me to any reference as to how to get them to work inside Processing? I'm extremely grateful for the help so far!

    The easiest way to get a ".jar" file for a sketch is what I said in my 1st reply to you here: :-\"

    If you got its ".jar" file, you can simply drag it into the Processing's IDE (PDE).

    That'll will copy the ".jar" file to a subfolder called "code/". B-)

    However, if you prefer to make it available for all sketches, you need to read this wiki: :-B

  • Thanks for all the help GoToLoop!
