Kn. Murty et Cv. Rao, Two-point boundary value problems associated with first order non-linear difference system - existence and uniqueness, APPL MATH C, 100(2-3), 1999, pp. 177-188
The general solution of the non homogeneous matrix difference system is est
ablished in terms of two fundamental matrix solutions by using the variatio
n of parameters formula. Uniqueness of solution to two point boundary value
problem is established by using modified QR algorithm and Barterls-Stewart
algorithm. (C) 1999 Elsevier Science Inc. All rights reserved.
