Abstract :
A new test is given for deciding whether a prescribed real polynomial of degree 
has all its zeros inside the unit circle. The test involves examination of the sign of various linear combinations of the polynomial coefficients, as well as examination to check positive definiteness of a symmetric matrix of dimensions 
when is even, and 
or 
when is odd.
has all its zeros inside the unit circle. The test involves examination of the sign of various linear combinations of the polynomial coefficients, as well as examination to check positive definiteness of a symmetric matrix of dimensions when is even, and or when is odd.Keywords :
