can be calculated by Eq. (8) for the second time.
In the remainder of the paper, the following 4 methods are
tried:
Method (1-1) matrix order m¼2 without modification Eq. (11),
using a1j
o14 in Eq. (8).
Method (1-2) matrix order m¼2 with modification Eq. (11),
using a1j
o24 in Eq. (8).
Method (2-1) matrix order m¼3 without modification Eq. (11),
using a1j
o14 in Eq. (8).
Method (2-2) matrix order m¼3 with modification Eq. (11),
using a1j
o24 in Eq. (8).
