NEWS:

  • The Final Exam is now available. It is due Friday, December 16th in the Math Office, room 100, Cupples I Hall, by 3:00 PM.

QUICK LINKS:

SAMPLE PROGRAMS:

  • Synthetic division Matlab function syndiv.m.
  • Sample code xcosx.txt to solve x=cos(x) by fixed-point iteration and plot the result.
  • Sample programs bin2dec.m and dec2bin.m to convert between binary and decimal integer formats.
  • eg-iter.txt: evaluate 20 terms of a two-term recurrence relation.
  • Sample program eulerdemo.m for Euler's method.
  • Function "nelder.m" as implemented in the textbook's software web site is buggy. Download a fixed nelder.m and use it instead. [Search for "CORRECTED" to find the two mistakes.]
  • Macsyma usage example macsyma.txt: formulas for the first 21 Chebyshev polynomials.
  • eg-plot3.txt: plot the edges of a cube.
  • Corrected help for Matlab programming for Sec.2.1, algorithm 1, p.51.

Syllabus

Topics. Computer arithmetic, error propagation, condition number and stability; mathematical modeling, approximation and convergence; roots of functions; calculus of finite differences; implicit and explicit methods for initial and boundary value problems; numerical integration; numerical solution of linear systems, matrix equations, and eigensystems; Fourier transforms; optimization. Various software packages are introduced and used.

Prerequisites. Math 1201 or equivalent programming experience, Math 217, and Math 309. NOTE: Students with credit for Math 404 or 405 [last taught in 2004] cannot also receive credit for 449.

Time. Classes meet Mondays, Wednesdays, and Fridays, 3:00 pm to 4:00 pm, in Cupples I Hall, Room 115.

Text. The lectures will follow John H. Matthews and Kurtis D. Fink, Numerical Methods Using MATLAB, fourth edition, ISBN 0-13-065248-2, Prentice Hall, 2003. Note: except for Chapters 5 and 8, the fourth edition is virtually identical to the third edition.

Homework. You are encouraged to collaborate on homework, and to work additional exercises from the indicated problem sections, although the homework grade will be based only on the exercises listed below. Please return your solutions to the instructor by the end of class. Problem sets will be assigned as follows:
Solutions are due at the end of class on the due date. Late homework will not be accepted. The problems will often require a complete proof. The homework will be judged for correctness and clarity. When the problem requires a computed solution, it must be accompanied by a correct, well-documented computer program which will be judged for its understandability. Please print and submit: (i) the program, with a comment for every line, (ii) the input you gave it, and (iii) the output it produced, for at least one example run.

Tests. There will be one midterm examination in class on Friday, October 21st, 2011. There will be one cumulative take-home final examination emphasizing the remaining material, due on Friday, December 16th, 2011 by 3:00 pm in the Mathematics Department Office, room 100, Cupples I Hall.

Grading. One score will be assigned for homework, one for the midterm examination, and one for the final examination. These three will contribute in respective shares of HW 50%, MT 20%, and FE 30% to the course score. Letter grades, computed from the course score class average and standard deviation, will be at least the following:

Course score at least:90%80%70%60%
Letter grade at least:ABCD

Students taking the Cr/NCr or P/F options will need a grade of D or better to pass.

Computing. Students are encouraged to use MATLAB and the computers available in the Arts and Sciences Computing Center for both symbolic and numerical computations. There is a free 1982 version of MatLab suitable for some of the homework assignments. A freeware imitation of current MatLab is also available, called Octave. It does not have the symbolic algebra functions of MatLab, but those are available within the freeware Macsyma system.

Office Hours. Mondays, 4-5pm, or by appointment, in Cupples I, room 105a.
