<h2>Magic Square Example</h2>
|
|
||||||
<p>
|
|
||||||
The Jama distribution comes with a magic square example that is used to
|
|
||||||
test and benchmark the LU, QR, SVD and symmetric Eig decompositions.
|
|
||||||
The example outputs a multi-column table with these column headings:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<table border='1' cellpadding='5' cellspacing='0' align='center'>

|
|
||||||
<td>Order of magic square.</td>
|
|
||||||
</tr>
|
|
||||||
<tr>
|
|
||||||
<td><b>trace</b></td>
|
|
||||||
<td>Diagonal sum, should be the magic sum, (n^3 + n)/2.</td>
|
|
||||||

|

The magic square example does not fare well when <a href='../examples/MagicSquareExample.php'>run as a PHP script</a>. For a 32x32 matrix array
|
|
||||||
it takes around a second to complete just the last row of computations in the above table.
|
|
||||||
Hopefully this result will spur PHP developers to find optimizations and better attuned algorithms
|
|
||||||
to speed things up. Matrix algebra is a great testing ground for ideas about time and memory
|
|
||||||
performance optimation. Keep in perspective that PHP JAMA scripts are still plenty fast for use as
|
|
||||||
a tool for learning about matrix algebra and quickly extending your knowledge with new scripts
|
|
||||||
to apply knowledge.

JAMA is a proposed standard matrix class for Java. The JAMA introduction
|
|
||||||
describes "JAMA : A Java Matrix Package" in this way:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<blockquote>
|
|
||||||
JAMA is a basic linear algebra package for Java. It provides user-level classes for
|
|
||||||
constructing and manipulating real, dense matrices. It is meant to provide sufficient
|
|
||||||
functionality for routine problems, packaged in a way that is natural and understandable
|
|
||||||
to non-experts. It is intended to serve as the standard matrix class for Java, and
|
|
||||||
will be proposed as such to the Java Grande Forum and then to Sun. A straightforward
|
|
||||||
public-domain reference implementation has been developed by the MathWorks and NIST as
|
|
||||||
a strawman for such a class. We are releasing this version in order to obtain public
|
|
||||||
comment. There is no guarantee that future versions of JAMA will be compatible with this one.
|
|
||||||
</blockquote>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The development team below has successfully ported the JAMA API to PHP. You can explore
|
|
||||||
this site to learn more about this project and it's current development status.

The first script your should run when you install Jama is the TestMatrix.php script.

This will run the unit tests for methods in the <code>Matrix.php</code> class. Because

the Matrix.php class can be used to invoke all the decomposition methods the <code>TestMatrix.php</code>
|

script is a test suite for the whole Jama package.

The original <code>TestMatrix.java</code> code uses try/catch error handling. We will
|
|
||||||
eventually create a build of JAMA that will take advantage of PHP5's new try/catch error
|
|
||||||
handling capabilities. This will improve our ability to replicate all the unit tests that
|
|
||||||
appeared in the original (except for some print methods that may not be worth porting).

You can <a href='../test/TestMatrix.php'>run the TestMatrix.php script</a> to see what
|
|
||||||
unit tests are currently implemented. The source of the <code>TestMatrix.php</code> script
|
|
||||||
is provided below. It is worth studying carefully for an example of how to do matrix algebra
|
|
||||||
programming with Jama.
