Detailed Description

template<BitPatternPropagationDirection BPPD>
struct ADOLC::Sparse::detail::BvpData< BPPD >

Internal data structure managing buffers and parameters for bit-vector propagation.

This struct encapsulates the state and storage used during the computation of Jacobian sparsity patterns using bit-vector propagation (BVP).

It manages seed matrices, temporary buffers, and strip-mining batches, depending on the chosen bit pattern propagation direction.

Template Parameters

BPPD	Direction of bit pattern propagation — Forward or Reverse.
