| Abstract: | This paper deals with a symmetric positive definite system of linear equations,which matrix of coefficients has a varying diagonal element with positive increment. A correctalgorithm is presented. The algorithm can be used in the iterative process of repeatedly solvingan above - mentioned system and improve efficiency of the process. |
