tobsr — SciPy v1.15.2 Manual (original) (raw)

scipy.sparse.bsr_matrix.

bsr_matrix.tobsr(blocksize=None, copy=False)[source]#

Convert this array/matrix into Block Sparse Row Format.

With copy=False, the data/indices may be shared between this array/matrix and the resultant bsr_array/bsr_matrix.

If blocksize=(R, C) is provided, it will be used for determining block size of the bsr_array/bsr_matrix.
