WHAT IS JNUMERIC? ----------------- JNumeric provides the functionality for JPython that Numeric does for CPython. As the Numeric documentation states, Numeric is "...a collection of extension modules to provide high-performance multidimensional numeric arrays to the Python programming language." JNumeric provides the same functionality as the core of Numeric module and aims to provide akk of the standard extensions to Numeric modules (FFT, LinearAlgebra, RandomArray). BUILDING --------- Go to src and type "make". The jar file should appear in the release directory. INSTALLATION (Hassan Siddiqui) ------------------------------ (This was an installation procedure suggested by Hassan.) Install jython, download jnumeric-XXX.jar, and add jython-XXX.jar to your $CLASSPATH'. You can then use JNumeric in jython in exactly the same way as you would use Numerical Python under Python (but check the DIFFERENCES.txt file). INSTALLATION (Recent-Linux with Java2 already installed) ------------------------------------------------------- First, make sure you get recent version from Github: > fill in Next, go build it! > ls jnumeric > cd jnumeric > ls CVS jnumeric > cd jnumeric > ls CHANGES.txt CVS lib README.txt src classes DIFFERENCES.txt LICENSE.txt release tests > cd src > make javac -classpath ../lib/jython.jar -d ../classes FFT.java Numeric.java JNumeric/BinaryUfunc.java JNumeric/JN_FFT.java JNumeric/Umath.java JNumeric/JNumeric.java JNumeric/PyMultiarray.java JNumeric/UnaryUfunc.java JNumeric/GeneralUfunc.java JNumeric/KeywordFunction.java JNumeric/PyMultiarrayPrinter.java cd ../classes; jar cf ../release/jnumeric-0.1a3.jar Numeric.class FFT.class JNumeric Next, install it! > cd .. > cd lib > su Password: > which java /opt/IBMJava2-131/bin/java > cp jython.jar /opt/IBMJava2-131/jre/lib/ext > cd .. > cd release > ls CVS jnumeric-0.1a3.jar > cp jnumeric-0.1a3.jar /opt/IBMJava2-131/jre/lib/ext > exit exit Next test it! > java org.python.util.jython *sys-package-mgr*: processing new jar, '/opt/IBMJava2-131/jre/lib/rt.jar' *sys-package-mgr*: processing new jar, '/opt/IBMJava2-131/jre/lib/i18n.jar' *sys-package-mgr*: processing new jar, '/opt/IBMJava2-131/jre/lib/ext/jnumeric-0.1a3.jar' *sys-package-mgr*: processing new jar, '/opt/IBMJava2-131/jre/lib/ext/ibmjcaprovider.jar' *sys-package-mgr*: processing new jar, '/opt/IBMJava2-131/jre/lib/ext/indicim.jar' *sys-package-mgr*: processing new jar, '/opt/IBMJava2-131/jre/lib/ext/jython.jar' Jython 2.1 on java1.3.1 (JIT: jitc) >>> from Numeric import * >>> a = array(10) >>> b = array( [[1,0],[0,1]]) >>> print b [[1 0] [0 1]] If you made it that far, you are ok! OBTAINING JNUMERIC ------------------ Our home page is found at http://jnumerical.sourceforge.net Also, please see the file DIFFERENCES.txt for a list of intentional differences between JNumeric and CNumeric. I highly recomend that you also download at JPython1.1b1 or later. Earlier versions of JPython have a fairly serious bug in getslice. WHENCE FROM HERE? ----------------- In addition to tracking down any bugs, here are a couple of things that I would like to do (or have done) with JNumeric at some point: * Add the standard extensions (FFT, LinearAlgebra, and RandomArray). * Cleaned up ufunc interface. * Other assorted code cleanup. I would realy love FFT, LinearAlgebra, or RandomArray code -- (if you're interested in working on LinearAlgebrea let me know I have some preliminary ideas for this).
