Numerical Analysis


Numerical Analysis. 4 Semester Hours.
An introduction to the numerical solution of mathematical problems. Primary emphasis is upon the development of use of computational algorithms to obtain an accurate numerical solution as well as methods for establishing error estimates and bounds for this solution. These algorithms will primarily be implemented on the computer using the Mathematica® system and a programming language such as C/C++, FORTRAN, or Pascal. Some work will also be done by using a scientific graphing calculator such as the TI-83 or TI-86. Grades will be based on assignments and exams. Prerequisites: MATH 202, MATH 205, COMP 150, and familiarity with the scientific graphing calculator. This course is cross-listed as MATH 320. Students may enroll in either COMP 320 or MATH 320, but not both. Mathematical-reasoning intensive.


The textbook for this course is Numerical Methods for Engineers, Third Edition, by Steven C. Chapra and Raymond P. Canale (McGraw-Hill).  Notes and handouts (through hardcopy and file access) will also be used.  You will have access to all the files in our COMP 320 course folder (subdirectory) on the Q-Drive during this course.  Selected class assignments, sample programs and data, and other guidelines will be stored in this folder.  You will be using several numerical analysis tools during this course including: a (TI) graphing calculator, a high-level language (C++, Fortran, or Pascal), and Mathematica® (Q:\Class Programs\Mathematica 4.bat).

All the references below are to the textbook unless otherwise indicated.  Since one prerequisite for this course is COMP 150, it is assumed that you are familiar with using high-level programming language constructs through the topic of 1-D and 2-D arrays.  It is also assumed that you are familiar with matrix algebra (MATH 205) as well as differential and integral calculus (MATH 201 and MATH 202).  All of these disciplines will be used during this course.

Course Goals:


Assignments (Including Possible Projects):

There will be two types of assignments: programming assignments that implement and or use numerical algorithms and analytical assignments to analyze properties of algorithms and errors.  Good program design, style and documentation are (still) important in all of the programming assignments.  Clear and precise logical steps and writing are important in all of the analytical assignments.  However, the main grading criteria is correctness.  If you have a question on any of the material you should raise it in class as soon as possible.  Assignments will be accepted in class.  They may also be turned in at my office by 5:00pm on the day assigned with no penalty.  After that, up to 10% of the total points possible will be DEDUCTED per day late (including weekends).  Assignments will not be accepted after three (3) days unless there is some type of emergency situation or special arrangements are made ahead of time.  Late assignments should be slid under my office door (or under the department door, if it is locked) - be sure my name is on it. 

Tests (Exams, Quizzes, and Final):

Exams and quizzes are typically (although not always) based upon what has been covered by lecture notes, assignments, handouts, and text material.  Exams and quizzes CANNOT be taken later without a legitimately excused absence (e.g., death in the family, personal illness, class field trip, necessary Witt-sponsored activity).  This excuse should be in writing (e.g., e-mail), and the instructor must be notified as far in ADVANCE as possible.

Grading:

The grade for this course will be based upon assignments and projects (up to 500 points), three equally-spaced tests (100 points each), and a comprehensive final examination (200 points).  Some of these points may also be obtained from unannounced quizzes. Assignments will be due by 5:00pm on the day assigned with up to 10% of the total points possible DEDUCTED per day late; assignments will not be accepted after three (3) days unless special arrangements have been made.  Quizzes are typically unannounced and cannot be taken later.  Exams cannot be taken later without advance notice and an official excused absence.  All programming assignments MUST initially be submitted with a new 3.5" diskette with a signed listing with the class account, date and time shown.  The diskette will contain the program itself as shown in the listing, and any necessary data files.  Class attendance and participation is very important and will have a positive effect on your grade.  The final grade for this course will be based upon the individual class average relative to the rest of the class.  If the score distribution starts in the 90%-100% range, then a ten-point spread will probably be used (e.g., 90% and above would be A-, A, or A+, 80% up to 90% is B-, B, B+, etc.). (Note: All point values are approximate.)

Academic Dishonesty:

Academic dishonesty of any kind on homework or exams is not acceptable.  This includes, but is not limited to, plagiarism or collaboration with another student on homework or tests.  At a minimum it will typically result in a reduced score (typically 0) for all parties involved and it could result in a failing grade for this course.  In addition, there may be other University sanctions. See your Student Handbook for additional details regarding Academic dishonesty.
