Detailed Description

template<class real_T = real>
class DNDS::MatrixBatch< real_T >

Packed variable-shape matrix-batch layout inside a flat buffer.

Each row of ArrayEigenMatrixBatch stores several matrices whose shapes may differ. MatrixBatch provides:

• nested UInt32PairIn64 / UInt16QuadIn64 helpers to pack two 32-bit (or four 16-bit) integers into a single 64-bit word (matrix shape headers);
• size computation (getBufSize) and compression (CompressIn) for an input vector of Eigen matrices;
• operator()(j) that returns an Eigen::Map onto the j-th matrix inside the already-compressed row buffer.

The templated real_T allows both mutable and const variants.
