The improved form of the conjugate gradients method (English)
0 references
A new form of representing the known method of conjugate gradients for solving of linear algebraic systems is found. It is turned out that the form proposed is the most simple and stable in relation to roundoff errors. A generalization of the method for problems with preconditioning is given.
