 * \section intro_sec Introduction
 *
 * LADEL is a package providing LDL and factorization update routines for sparse matrices.
 * 
 * \section install_sec Installation
 * Please see the @ref installation-md page.
 * 
 * \section example Using LADEL (in Matlab)
 * 
 * Using LADEL from Matlab is simple. Here is an example
 * \code{.unparsed}
 * %% Generate data
 * n = 10;
 * M = sprand(n,n, 1e-1, 1) + 2*speye(n);
 * M = (M+M')/2; %make sure M is symmetric
 * x = rand(n,1);
 * 
 * %% Example 1: factorize and solve
 * solver = ladel(n);
 * solver.factorize(M);
 * y = solver.dense_solve(x);
 * assert(norm(y-M\x) < 1e-12);
 * \endcode
 * 
 * You can find many other examples in LADEL/mex/demos.
