Abstract

We present some matrix and determinant identities for the divided differences of the composite functions, which generalize the divided difference form of Fa\`{a} di Bruno's formula. Some recent published identities can be regarded as special cases of our results.

Key words: Bell polynomial, Composite function, Determinant identity, Divided difference, Matrix identity.
