Expand description

Detailed statistics about the block-level sparsity of a BSR tensor.

Fields§

§total_blocks: usize

Total number of possible blocks.

§nnz_blocks: usize

Number of stored (non-zero) blocks.

§sparsity: f64

Fraction of blocks that are zero (1 − density).

§density: f64

Fraction of blocks that are non-zero (1 − sparsity).

§memory_bytes: usize

Actual memory used by the BSR representation (bytes).

§theoretical_dense_bytes: usize

Memory a fully dense f64 matrix would require (bytes).

§compression_ratio: f64

theoretical_dense_bytes / memory_bytes. Values > 1.0 indicate savings.

§avg_block_norm: f64

Mean Frobenius norm of stored blocks.

§max_block_norm: f64

Maximum Frobenius norm among stored blocks.
