In this tutorial we are going to implement this method using C programming language. During the first iteration, the value of i is initiated to 1, now digging deep we will encounter a if statement whose condition is if the remainder of the given number vs the iterator is 0 then the condition is satisfied and you can go inside to execute the next line of come again after you have changed your value. Newton's method is sometimes also known as Newton's iteration , although in this work the latter term is reserved to the application of Newton's method for. Thereafter we focus on the evalua-tion of an effective number of iteration vectors. In mathematics, the conjugate gradient method is an algorithm for the numerical solution of particular systems of linear equations, namely those whose matrix is symmetric and positive-definite. 3 (GaussSeidel Iterative Method) cg.
