If H is an UK space which has AD property, then we define the matrix A(H)= (a mn ) as a n.,"=< e m ,e n>H.. We prove that A(H) is uniquely determined by H , and hence conclude that there is a one - to - one map between the collection of all 1-11C spaces which have AD, and that of all matrices which are positive definite and Hermitian. Finally , we calculate A(H 2 1w) where W--(d n ) is an interpolating sequence. j aido
