Detailed Description

template<typename T_value>
class Hpro::TACAFull< T_value >

     Full ACA tests <em>all</em> matrix coefficients in the search for the
     best cross. This results in a guaranteed approximation within the given
     accuracy. However, the costs are now quadratic in the size of the block.
