چكيده فارسي :
In designing general linear methods for the numerical soluition of ODEs, a concept known as algebraic stability s dened based on a non-linear test problem. By this concet, the behavior of the methods applying to the non-linear problems is analyzed. In this paper, we discuss the role of positive denite matrices in dening the algebraic stability and its properties.
