111 Implementation of <A HREF="../../../../../org/apache/commons/math/linear/BigMatrix.html" title="interface in org.apache.commons.math.linear"><CODE>BigMatrix</CODE></A> using a BigDecimal[][] array to store entries
|
|
|
112 and <a href="http://www.math.gatech.edu/~bourbaki/math2601/Web-notes/2num.pdf">
|
|
|
113 LU decompostion</a> to support linear system
|
|
|
114 solution and inverse.
|
|
|
115 <p>
|
|
|
116 The LU decompostion is performed as needed, to support the following operations: <ul>
|
|
|
117 <li>solve</li>
|
|
|
118 <li>isSingular</li>
|
|
|
119 <li>getDeterminant</li>
|
|
|
120 <li>inverse</li> </ul></p>
|
|
|
121 <p>
|
|
|
122 <strong>Usage notes</strong>:<br>
|
|
|
123 <ul><li>
|
|
|
124 The LU decomposition is stored and reused on subsequent calls. If matrix
|
|
|
125 data are modified using any of the public setXxx methods, the saved
|
|
|
126 decomposition is discarded. If data are modified via references to the
|
|
|
127 underlying array obtained using <code>getDataRef()</code>, then the stored
|
|
|
128 LU decomposition will not be discarded. In this case, you need to
|
|
|
129 explicitly invoke <code>LUDecompose()</code> to recompute the decomposition
|
|
|
130 before using any of the methods above.</li>
|
|
|
131 <li>
|
|
|
132 As specified in the <A HREF="../../../../../org/apache/commons/math/linear/BigMatrix.html" title="interface in org.apache.commons.math.linear"><CODE>BigMatrix</CODE></A> interface, matrix element indexing
|
|
|
133 is 0-based -- e.g., <code>getEntry(0, 0)</code>
|
|
|
134 returns the element in the first row, first column of the matrix.</li></ul></p>
