Perfect matrix
In
mathematics
, a
perfect
matrix
is an
m
-by-
n
binary matrix
that has no possible
k
-by-
k
submatrix
K
that satisfies the following conditions:
k
> 3
the
row
and
column
sums
of
K
are each
equal to
b
, where
b
≥ 2
there exists
no row of the -by-
k
submatrix formed by the rows not included in
K
with a row
sum
greater than
b
.
The following is an example of a
K
submatrix where
k
= 5 and
b
=
2:
