摘要：

A new type of layer matrix, called R matrix, was constructed on the basis of distance sums of vertices. This matrix was operated with two classes of operators: one of ''centricity'' (''c'') type and the other of ''centrocomplexity'' (''x'') type, the last one taking into account the ''more important'' vertices in molecular graphs. The matrix invariants are computed with a TURBO PASCAL, TOPIND 10 program for various examples, and finally an intercorrelating matrix is given for the proposed topological indices in the set of heptane isomers.
