In this work, we have transformed the multivariate to unitevariate system, and studied the elimination and duplication matrices, using proposed approach depends on some algebra principle. And, a connection has been made between these two matrices with each of the ( υec ) and ( υ ) operators for matrices. Several examples are given to illustrate the applications which is used to define and specialize the elimination and duplication matrices.
