setdiag(values, k=0)
Fills the diagonal elements {a_ii} with the values from the given sequence. If k != 0, fills the off-diagonal
elements {a_{i,i+k}} instead.
values may have any length. If the diagonal is longer than values, then the remaining diagonal entries will
not be set. If values if longer than the diagonal, then the remaining values are ignored.
sort_indices()
Sort the indices of this matrix in place
sorted_indices()
Return a copy of this matrix with sorted indices
sum(axis=None)
Sum the matrix over the given axis. If the axis is None, sum over both rows and columns, returning a
scalar.
sum_duplicates()
Eliminate duplicate matrix entries by adding them together
The is an in place operation
toarray()
tobsr(blocksize=None, copy=True)
tocoo(copy=True)
Return a COOrdinate representation of this matrix
tocsc()
When copy=False the index and data arrays are not copied.
tocsr(copy=False)
todense()
todia()
todok()
tolil()
transpose(copy=False)
class bsr_matrix(arg1, shape=None, dtype=None, copy=False, blocksize=None)
Block Sparse Row matrix
This can be instantiated in several ways:
bsr_matrix(D, [blocksize=(R,C)])
with a dense matrix or rank-2 ndarray D
