Advanced math library for java needed.

Hi,
I need to perform nonlinear regression in order to fit a function to a set of datapoints (five parameters to estimate simultaneously).
Does anyone know of a library for Java that can perform this? I have not been able to find something myself so far.
Thanks in advance!

Here's a thought, kind of whacky and off the wall, but ... build it yourself?
Just a thought.

  • PS Library for Java?

    Does Adobe have a postscript print library for Java?
    I called Adobe Support - and got the typical India call center (no help of course). Hopefully Adobe has smart people someplace in the company... just not sure where.
    We have a Java Web Start desktop client for geospatial work that we need to add postscript support for large format printing (e.g. E size drawings). The goal is decrease print times over the normal Java2D/Windows "render a bitmap image on the client - then send it to the print server - then to the printer" method by creating a small postscript file to send to the printer - that can then create the large bitmap to print at the device.
    From what I can tell Adobe has no such library - is that really true?
    If so - does anyone have recomendations on a good solid commercial or open source library?
    Google seaches come up with only a couple (e.g. RiePS), none of which sound very robust. Does no one develep applications to output to postscript any more?
    Thanks in advance...

    Assuming that you are lookng for a library for creation of PostScript, no, Adobe offers no libraries for PostScript creation in Java or otherwise.
    Most applications in common operating systems environements (Windows, MacOS, etc.) rely on the operating system's internal graphics model and the provided PostScript driver to generate PostScript for the particular device and deliver same over the device's communication channel (Ethernet, USB, etc.).

  • Need 9.0 SDK library for java

    We have crystal enterprise server 8.5 & using IBM RAD 6.0 for java based client development. i believe RAD by default gets 10.0 SDK with which we are getting unsupported enterprise version exception.
    At this moment we are not upgrading enterprise server to higher version. i was looking for older SDK versions in Business object's SDK library page... but vouldn't find any older version SDK.
    If any one has exact information about where can i get older version (9.0) SDK libraries would be of great help
    Thanks & Regards,
    Rajendra

    I don't believe that there were any jars for 8.5 - that was introduced in version 9.  If you have an install of version 9 - you can find the jar files in the javasdk folder located in c:\program files\common files\Crystal Decisions\2.0\  ( I believe that's the correct folder - I'm going from memory)

  • JSON Library for Java

    Hi folks,
    I have found few JSON libraries for Java such as Google and json.org. Would anyone recommend a good one for me, thanks!

    I have been using that library (org.json) for about 3 months. It is simple and I haven't found any bugs.
    There isn't much to JSON so I wouldn't expect one library to much different than another.

  • Free Constraint Programming Library for Java?? what to use?

    Hi everyone,
    I am currently programming the popular Sudoku game as my final year project at university. After doing some research I found that using Constraint Programming would be the best way to generate and solve the Sudoku puzzles... however, I'm in a bit of a dilemma....
    I'm not sure what Constraint Library to use - the most popular one out there is Koalog - but its a commercial application - and I was looking for an open source or free application.
    I have been looking into the Choco (http://choco.sourceforge.net) Library but I am having trouble with getting hold of the global constraints I need ie AllDifferent.
    An extensive guide of how to use Constraint Programming is shown on the Java Sun Website: http://today.java.net/pub/a/today/2005/11/29/solving-sudokus-in-java.html
    Any advise would be greatly appreciated.
    Thanks in advance
    :o)

    Hi aniseed,
    Thanks for the user guide link -- I have looked through and I am beginning to understand it all.... but my main problem is that the user guide specifies a global constraint called allDifferent
    Here are described som of those constraints :
    1. pb.allDifferent(IntVar[] vars) creates a constraint ensuring that all pairs of variable
    have distinct values (which is useful for some matching problems)When I try to type pb.allDifferent into my program - it does not recognise the method so it does not compile- all the other methods work apart from this one.
    Any ideas?? :o)

  • Java library for large list sorts in small amount of memory

    Hi All
    Wondering whether anybody would know of a ready made java library for sorting large lists of objects. We will write ourselves if necessary but I'm hoping this is the sort of problem that has been solved a million times and may hopefully have been wrapped behind some nice interface
    What we need to do is something along the line of:
    Load a large list with objects (duh!)
    If that list fits into an allowed amount of memory great. Sort it and end of story.
    If it won't then have some mechanism for spilling over onto disk and perform the best sort algorithm possible given some spill over onto disk.
    These sorts need to be used in scenarios such as a random selection of 10% of the records in a 100G unsorted file and delivered sorted, with the jobs doing the sorts being limited to as little as 64MB of memory (these are extremes but ones that happen quite regularly).
    Some of you might think "just use a database". Been there. Done that. And for reasons beyond the scope of this post its a no goer.
    Thanking you for all your help in advance.

    Of course this kind of sorting was common back in days of yore when we had mainframes with less than 1MB or ram.
    The classic algorithm uses serveral files.
    1) Load as much as will fit
    2) sort it
    3) Write it to a temporary file
    4) Repeat from 1, altnerating output between two or three temp files.
    Your temporary files then each contain a series of sorted sequences (try saying that three times fast).
    You then merge these sequences into longer sequences, creating more temp files. Then merge the longer sequences into even longer ones, and so on until you're left with just the one sequence.
    Merging doesn't require any significant memory use however long the sequences. You only need to hold one record from each temp file being merged.

  • Global java-library for graphical mapping?

  • Why do we need IDE or tools for java card programming?

    Hi,
    I am a newbie to java card, using java card kit tools themself, we can test and burn the code into card right?
    then why do we need IDE for java card, please correct me , if i am wrong,
    Thanks in advance,
    Sri.

    Dear Sri,
    We have compiler, linker etc for every language starting of from C or C++ or Java. JDK has all the tools necessary to develop and run a Java program. Similarly Java Card Development Kit has all the tools for developing and deploying a Java Card applet. But what an IDE does is too integrate all these tools and make it easier for the JavaCard programmer to develop his applets. Just like Eclipse is used for Java applet development.And not everytime the code is burned to the card. Its only during masking code is burned to the card, i.e if u can call it burning. Masking makes an applet permanent on the card.
