Detailed Description

Accumulator for H-matrix products.

In order to reduce the number of SVD computations, we can accumulate updates to the same submatrix in an auxiliary structure. Low-rank updates are accumulated in an rkmatrix object, while structured updates are entered into a list of hprodentry objects.

The documentation for this struct was generated from the following file:
