Cheg 258 - Lecture Notes - March 30, 2001

Announcements

The problems assigned today are review questions for the exam a week from Wednesday.

Class notes

The main points of the lecture were

• Romberg Iteration

Goals:

• Combine low degree quadrature rules to get high degree rules with no additional function evaluations.
• Understand what these methods imply to error in integration of noisy data.

Reading

• The class notes and Chapter 5 of Kahaner and Chapter 11 of Recktenwald.

Question of the Day

• Why is an estimate of the error of integration important?
• How can you estimate the contribution of error in function evaluation to the error in the integral?
