Detailed Description

template<typename _t_value>
class CBICRS_factory< _t_value >

Factory for the Compressed Bi-directional Incremental Compressed Row Storage scheme.

Auto-tunes index type (signed char, short int, int or long int). May revert back to a plain BICRS implementation.

Warning: assertions may be used! For optimal performance, define the NDEBUG flag (pass -DNDEBUG as a compiler flag).
