Abstract

The classical Hermite formula for polynomial interpolation is generalized to interpolation of vector polynomials (tangential interpolation). The formula exhibits a relation between the matricial homogeneous problem and the nonhomogeneous vector problem. As applications, a formula for the inverse of a generalized Vandermonde matrix is presented and it is shown that the well-known formulas for the inverse of a Toeplitz matrix can be obtained as a special case of the generalized Hermite formula.
