The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup. Firstly we know the MATLAB uses double precision, from binary number, we could find the smallest possible number that Matlab could use. $x_s=m\beta^{e}$, let $e=-1022$, m has at most $52$ digits, This works pretty good... navigate here

Player claims their wizard character knows everything (from books). You have been tasked with developing an M-file that allows other engineers to quickly determine the maximum n needed to reduce the truncation error below an error threshold. All they can measure is how well they are doing on fitting that _particular_ function, how close they are getting to 0 and how quickly it is converging for that _particular_ Nov 14 '11 at 15:08 @J.M.

You used the value of n that would work for an exponential series. M. Play games and win prizes!

For what values of x does it produce poor approximations? Also, hand in any paper-and-pencil analysis you did for the exercises. Shampine,I. Round Off Error Discover...

Each chapter begins with a discussion of the "facts of life" for the problem, mainly by means of examples. Taylor Series Matlab Code Play games and win prizes!

You cannot numerically calculate the truncation error of arbitrarily complex functions.For example, suppose the function calculates the number of Odd Perfect Numbers, and suppose the solution come out with is 0.

The value of n here is appropriate for the exponential series, and since the cosine series essentially uses the even order terms from the exponential one, this could work, IF you Exercise 1: Explain what is happening in this graph, based on the notions of truncation and round-off error.

thanks and sorry to bother you . Is the ability to finish a wizard early a good idea? Prerequisites are a first course in the theory of ODEs and a survey course in numerical analysis, in addition to specific programming experience, preferably in MATLAB, and knowledge of elementary matrix
