In this paper, the hypergeometric matrix differential equation z( 1 -t)W" -zAW' + W'(C -z(B + I)) -AWB = 0 is studied. First it is proved that if matrix C is invertible and no negative integer is one of its eigenvalues, then the hypergeometric matrix function F(A, B; C; z) is an analytic solution in
