3. Errors (Uncertainties) in Computations

Uncertainties ("errors") are an inevitable part of computation with floating point numbers. This lecture analyzes the different types of errors that occur and provide some practical techniques to measure their importance. This is just one of 61 Lectures covering a full one-year Course in Computational Physics previously taught by Rubin Landau at Oregon State University. (The number refers to the chapter and section in reference 1 below.) There are video modules (Flash), slides, codes, quizzes, and all the lectures at: http://sites.science.oregonstate.edu/~landaur/Books/CPbook/eBook/Lectures/ The YouTube playlist with all videos is at: https://www.youtube.com/playlist?list=PLnWQ_pnPVzmJnp794rQXIcwJIjwy7Nb2U References: 1.
