scipy.sparse.lil_matrix.tobsr#

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

Convert this array/matrix to Block Sparse Row format.

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

When blocksize=(R, C) is provided, it will be used for construction of the bsr_array/matrix.
