In this paper we obtain a Nevanlinna-type formula for the matrix Hamburgermoment problem in a general case. We only assume that the problem is solvableand has more that one solution. We express the matrix coefficients of thecorresponding linear fractional transformation in terms of the prescribedmoments. Necessary and sufficient conditions for the determinacy of the momentproblem are given.
