20 * \brief Householder rank-revealing QR decomposition of a matrix with column-pivoting
24 * This class performs a rank-revealing QR decomposition of a matrix \b A into matrices \b P, \b Q and \b R
32 * This decomposition performs column pivoting in order to be rank-revealing and improve
166 * For rank-deficient matrices, use
168 * matrixR().topLeftCorner(rank(), rank()).template triangularView<Upper>()
