	Construct a view from raw pointers. Intended for internal use by `Array::view()`.

DNDS_DEVICE_CALLABLE bool	isCompressed () const
	Whether the underlying array is in the compressed (flat) form (always true for non-CSR).

DNDS_DEVICE_CALLABLE index	Size () const
	Number of rows in the viewed array.

DNDS_DEVICE_CALLABLE rowsize	RowSize () const
	Uniform row width for fixed layouts (asserts otherwise).

DNDS_DEVICE_CALLABLE rowsize	RowSize (index iRow) const
	Per-row width. Handles CSR compressed and decompressed modes.

DNDS_DEVICE_CALLABLE rowsize	RowSizeMax () const
	Maximum row width (TABLE_*Max only).

DNDS_DEVICE_CALLABLE rowsize	RowSizeField () const
	"Logical" row-field width used by derived Eigen arrays; see Array::RowSizeField.

DNDS_DEVICE_CALLABLE rowsize	RowSizeField (index iRow) const
	Per-row "field" size for CSR (= actual row width).

const T &	at (index iRow, rowsize iCol) const
	Bounds-checked element read (not device-callable because CSR decompressed uses `std::vector::at` which throws on the host).

T &	operator() (index iRow, rowsize iCol=0)
	2D indexed access (writable). See `at`.

const T &	operator() (index iRow, rowsize iCol=0) const
	2D indexed access (read-only).

T *	operator[] (index iRow)
	Raw row pointer. `iRow == Size()` is allowed for past-the-end queries (useful for computing buffer end in sweeps).

const T *	operator[] (index iRow) const
	Const row pointer; see the non-const overload.

DNDS_DEVICE_CALLABLE T *	data ()
	Raw pointer to the start of the flat data buffer.

DNDS_DEVICE_CALLABLE size_t	DataSize () const
	Size of the flat data buffer in `T` elements.

DNDS_DEVICE_CALLABLE bool	operator== (const self_type &R) const
	Pointer equality (two views referring to the same buffer).

Detailed Description

template<DeviceBackend B, class real_T, int _n_row, int _n_col>
class DNDS::ArrayEigenUniMatrixBatchDeviceView< B, real_T, _n_row, _n_col >

Device-callable view onto ArrayEigenUniMatrixBatch rows.

operator()(i, j) returns an Eigen::Map<Matrix<real, _n_row, _n_col>> pointing at the j-th matrix of row i's batch. BatchSize(i) reports the batch count (not the raw CSR width).
