A New Iterative Algorithm for Linear Equation

CHANG Shuang-lingBeijing Wuzi University,Beijing 101149,China  
Using the sum of the elements of the principal diagonal of the coefficient matrix A,a new iterative scheme,i.e.xk+1=I-2a11+…+annAxk+2a11+…+annb,is constructed for the linear equation Ax=b,of which the coefficient is a symmetric positive definite matrix.Further improvement is made of the scheme.
