Commentary on an open question

摘要

In this commentary, we give the triangular recurrence relations for the elements of the matrix T = (Ti,j) = L1D−1S1 and its inverse T-1=(T¯i,j)=S2DL1-1, respectively, which have also answered the open question put forward by El-Mikkawy. Moreover, with the recurrences, a computational MAPLE program is written to generate the elements of T and T−1.
