INSTALL
-------

In principle, all you need is the jblas-1.2.5.jar in your
classpath. jblas-1.2.5.jar will then automagically extract your platform
dependent native library to a tempfile and load it from there. You can
also put that file somewhere in your load path ($LD_LIBRARY_PATH for
Linux, %PATH for Windows).

Or, use the following dependency in maven

```HTML
  <dependency>
    <groupId>org.jblas</groupId>
    <artifactId>jblas</artifactId>
    <version>1.2.5</version>
  </dependency>
```

BUILDING
--------

If you only work on the java part, you can use maven to recompile from the sources.
In addition to that you need an installation of
ruby for some scripts which automaticall generate code. Then, you just
type "mvn package" on the command line.

If you want to build jblas from the sources including the native part,
you need to set up quite a few things:

You will need some implementation of blas and lapack. jblas is tested
with either plain lapack, or ATLAS
(http://math-atlas.sourceforge.net/). You also need the Fortran
sources for BLAS and LAPACK, available, for example from
http://www.netlib.org/lapack/lapack-lite-3.1.1.tgz.

If you still want to build the source your own, see INSTALL for
further details.

HOW TO GET STARTED
------------------

Have a look at javadoc/index.html and
javadoc/org/jblas/DoubleMatrix.html

If you want to validate your installation and get some performance
numbers, try "java -jar jblas-1.2.5.jar".
