A few features of this matrix are apparent from the following:
T(4, :) - T(1, :) - T(2, :) - T(3, :)
T(9, :) - T(5, :) - T(6, :) - T(7, :) - T(8, :)
T(10, :) - T(4, :) - T(9, :)
T(10, 1:4) - T(1:4, 9)'

Thus the 4th row, which summarizes inter-industry inputs, is the sum of the
first three rows; the 9th row, which summarizes “primary inputs,” is the sum
of rows 5 through 8; the 10th row, total inputs, is the sum of rows 4 and 9,
and the first four entries of the last row agree with the first four entries of
the last column (meaning that all output from the industrial sectors is
accounted for). Also we have
(T(:, 4) - T(:, 1) - T(:, 2) - T(:, 3))'
(T(:, 8) - T(:, 5) - T(:, 6) - T(:, 7))'
(T(:, 9) - T(:, 4) - T(:, 8))'
