Detailed Description

Tree structure representing a $\mathcal{DH}^2$-matrix.

If u is not null, we are dealing with an admissible submatrix represented as $V_{tc} S_{ts} W_{sc}^*$, where the row basis $V_{tc}$ and the column basis $W_{sc}$ are given by rb and cb, respectively, and $S_{ts}$ is contained in u.

If f is not null, we are dealing with an inadmissible leaf represented directly by f.

If son is not null, the matrix is subdivided into rsons row sons and csons column sons. The pointer to the submatrix in the i-th row and the j-th column can be found son[i+j*rsons].
