\returns A const reference to the vectors containing the alpha values * * This vector permits to reconstruct the j-th eigenvalues as alpha

Performs a symbolic decomposition on the sparcity of \a matrix. * * This function is particularly useful when solving for several problems

Like at(), but the search is performed in the range [start,end) */

\returns A const reference to the vectors containing the beta values * * This vector permits to reconstruct the j-th eigenvalues as alphas

\returns a dynamic-size expression of a bottom-left corner of *this. * * \param cRows the number of rows in the corner * \param cCols the number

\returns a dynamic-size expression of a bottom-right corner of *this. * * \param cRows the number of rows in the corner * \param cCols the numbe

\returns a block consisting of the bottom rows of *this. * * \param n the number of rows in the block * * Example: \include MatrixBase_bottomR

\returns the center of the box */
