<P>
Implementation of RealMatrix using a double[][] array to store entries and
 <a href="http://www.math.gatech.edu/~bourbaki/math2601/Web-notes/2num.pdf">
 LU decomposition</a> to support linear system
 solution and inverse.
 <p>
 The LU decomposition is performed as needed, to support the following operations: <ul>
 <li>solve</li>
 <li>isSingular</li>
 <li>getDeterminant</li>
 <li>inverse</li> </ul></p>
 <p>
 <strong>Usage notes</strong>:<br>
 <ul><li>
 The LU decomposition is cached and reused on subsequent calls.
 If data are modified via references to the underlying array obtained using
 <code>getDataRef()</code>, then the stored LU decomposition will not be
 discarded.  In this case, you need to explicitly invoke
 <code>LUDecompose()</code> to recompute the decomposition
 before using any of the methods above.</li>
 <li>
 As specified in the <A HREF="../../../../../org/apache/commons/math/linear/RealMatrix.html" title="interface in org.apache.commons.math.linear"><CODE>RealMatrix</CODE></A> interface, matrix element indexing
 is 0-based -- e.g., <code>getEntry(0, 0)</code>
 returns the element in the first row, first column of the matrix.</li></ul>
