ITERATIVE METHODS

Iterative methods: Starting with an initial guess, say x0and generating a sequence   x1, x2, x3, . . . recursively from any relation is called an Iterative method.
 

Convergence : Any iterative process defined by xi+1= g(xi), i = 0, 1, 2, . . . is said to be convergent for the initial guess x0 if the corresponding sequence x1, x2, x3, . . . converges.
