 This change looks suspicious, can you justify it:
@@ 1927,6 +1928,7 @@ def block_matrix(*args, **kwds): sub_matrices = args[0] if is_Matrix(sub_matrices): + M = sub_matrices # a single matrix (check nrows/ncols/ring) if (nrows is not None and nrows != 1) or \ (ncols is not None and ncols != 1):
If it's a bug fix, then a doctest should be added.
 Replace
if ring == QQ or ring == ZZ:
byif ring is QQ or ring is ZZ:
 PEP 8 recommends to write
entries = lambda i, j: 1 / (i + j + 1)
as
def entries(i, j): return 1 / (i + j + 1)

About 1. Pyflakes said that M was not defined anywhere. And indeed, this part of the code was not doctested.
 and 3. Done

Looks good to me.
Side Note : This ticket is actually a bug fix with the M = sub_matrices
modification.
