<hr><a name="_details"></a><h2>Detailed Description</h2>
<h3>template<typename TMatrix, typename TVector, typename TEigenMatrix = TMatrix><br>
class itk::SymmetricEigenAnalysis< TMatrix, TVector, TEigenMatrix ></h3>
Find Eigen values of a real 2D symmetric matrix. It serves as a thread safe alternative to the class: vnl_symmetric_eigensystem, which uses netlib routines.
<p>
The class is templated over the input matrix, (which is expected to provide access to its elements with the [][] operator), matrix to store eigen values, (must provide write operations on its elements with the [] operator), EigenMatrix to store eigen vectors (must provide write access to its elements with the [][] operator).<p>
The <a class="el" href="classitk_1_1SymmetricEigenAnalysis.html#7940261268fb1ec182b94a5e4eebb345">SetOrderEigenValues()</a> method can be used to order eigen values (and their corresponding eigen vectors if computed) in ascending order. This is the default ordering scheme. Eigen vectors and values can be obtained without ordering by calling SetOrderEigenValues(false)<p>
The <a class="el" href="classitk_1_1SymmetricEigenAnalysis.html#01cf8d66b94ed4992154de9ec297e6ee">SetOrderEigenMagnitudes()</a> method can be used to order eigen values (and their corresponding eigen vectors if computed) by magnitude in ascending order.<p>
The user of this class is explicitly supposed to set the dimension of the 2D matrix using the <a class="el" href="classitk_1_1SymmetricEigenAnalysis.html#0e491bba952259d5f0f06fd1f5965959">SetDimension()</a> method.<p>
The class contains routines taken from netlib sources. (www.netlib.org). netlib/tql1.c netlib/tql2.c netlib/tred1.c netlib/tred2.c<p>

Compute Eigen values and vectors of <a class="el" href="classA.html">A</a> <a class="el" href="classA.html">A</a> is any type that overloads the [][] operator and contains the symmetric matrix. In practice only the upper triangle of the matrix will be accessed. (Both <a class="el" href="classitk_1_1Matrix.html" title="A templated class holding a M x N size Matrix This class contains a vnl_matrix_fixed...">itk::Matrix</a> and <a class="el" href="classvnl__matrix.html">vnl_matrix</a> overload [][] operator.)<p>
'EigenValues' is any type that overloads the [] operator and will contain the eigen values.<p>
'EigenVectors' is any type that provides access to its elements with the [][] operator. It is expected be of size m_Dimension * m_Dimension.<p>
No size checking is performed. <a class="el" href="classA.html">A</a> is expected to be a square matrix of size m_Dimension. 'EigenValues' is expected to be of length m_Dimension. The matrix is not checked to see if it is symmetric.<p>
Each row of the matrix 'EigenVectors' represents an eigen vector. (unlike MATLAB where the columns of the [EigenVectors, EigenValues] = eig(A) contains the eigenvectors).
