- jax.experimental.sparse.bcsr_fromdense(mat, *, nse=None, n_batch=0, n_dense=0, index_dtype=<class 'jax.numpy.int32'>)[source]#
Create BCSR-format sparse matrix from a dense matrix.
- Parameters:
mat (ArrayLike) – array to be converted to BCOO.
nse (int | None) – number of stored elements in each batch
n_batch (int) – number of batch dimensions (default: 0)
n_dense (int) – number of dense dimensions (default: 0)
index_dtype (DTypeLike) – dtype of sparse indices (default: int32)
- Returns:
BCSR representation of the matrix.
- Return type:
mat_bcsr
