ABSTRACT
The stability problem for a class of retarded delay differential systems is considered in this paper. The time delay (h) was assumed a variable and the asymptotic criteria was contrived. Test was formulated in the form of a scalar positive matrix functional and its application to numerical problems confirmed the suitability of this test.
