CATALOG DESCRIPTION:
174/274. Numerical Methods for Physical Modeling (4)
Floating point arithmetic, direct and iterative solution of linear
equations, iterative solution of nonlinear equations, optimization,
approximation theory, interpolation, quadrature, numerical methods for
initial and boundary value problems in ordinary differential equations.
(Students may not receive credit for both Math 174 and PHYS 105,
AMES 153 or 154. Students may not receive credit for Math 174 if
Math 170A, B, or C has already been taken.) Graduate students will do
an extra assignment/exam.
Prerequisites: Math 20D or Math 21D, and either Math 20F or Math 31AH,
or consent of instructor.
COURSE INFORMATION:
Many of the advances of modern science have been made possible only through
the sophisticated use of computer modeling.
The mathematical foundation of the computer modeling techniques now used
in all areas of mathematics, engineering, and science is known as
numerical analysis.
The Math 174/274 at UCSD provides a quick but thorough introduction to the
exciting field of numerical analysis, which is also sometimes referred to as
computational mathematics or scientific computing.
Professor Holst has a passion for this particular area of mathematics,
and much of his published research is in this area.
Math 174/274 deals primarily with the development and analysis of algorithms
(or, numerical methods) for solving systems of linear systems of equations,
nonlinear systems of equations, optimization problems, and ordinary
differential equations, and for approximating functions, their derivatives,
and their integrals.
GRADES, HOMEWORKS, EXAMS, AND IMPORTANT DATES:
Course information, such as homework assignments, due dates, and exam dates,
will be maintained on the class webpage.
Note that I sometimes make minor changes to the homework assignments as
the quarter progresses, based on how much I am able to cover in the lectures.
Therefore, CHECK THE WEBPAGE FREQUENTLY.
The course will be graded on the homework assignments, two midterm
examinations and a final examination, according to the following
guidelines:

Written and Computer HW (five homeworks): 

20% of grade 

Midterm #1 (In class, end of week 3): 

20% of grade 

Midterm #2 (In class, end of week 7): 

20% of grade 

Final Exam (Wednesday 12/17/14, 3pm5:59pm, APM 5402) 

40% of grade 
Here are some other important dates:

First lecture: 

FRI 10/03 

Last lecture: 

FRI 12/12 

Finals week: 

MONFRI, 12/1512/19 

Holiday: 

FRI 11/28 (Thanksgiving Break  NO LECTURE) 

Final Exam: 

WED 12/17, 3pm5:59pm, APM 5402 
There will be five homework assignments throughout the quarter.
The first midterm will be based on homeworks 1 and 2.
The second midterm will be based on homeworks 3 and 4.
The final will be cummulative and based on homeworks 14,
as well as a small amount of new material from homework 5.
The following policies regarding homeworks and exams will be applied:
 I normally do not accept late homeworks so that I can post solutions
to the homeworks in a timely way for the class.
 The default plan is to have all HW assignments count towards the
final grade in the class. However:
THE "DEAL" 12/08/2014:
As announced in class,
if we can hit a target of 70% of the class giving a CAPE response, then
in return for your help with getting a good sample size for the CAPES,
I will drop your single lowest homework score for the quarter.
Your grade for the homework in the class will then be the average
of just your four best scores.
UPDATE 12/17/2014:
The CAPE response rate has now exceeded our target
of 70% (we hit 79% last night).
As promised, in return for your help with getting a good sample size
for the CAPES, I will now drop your single lowest homework score.
Your grade for the homework will then be the average of just your four
best scores.
Thanks again to all of you for helping get a good CAPE response;
I read every single comment, and I make changes in the way I teach
every year based on what you write.
 In order to receive credit on a homework, you must at least attempt
the computer parts of the homework assignments (if there are any).
 There will be no makeup exams. If you miss a midterm with
an excused absence (i.e., illness with a note from a doctor), the
other midterm and the final exam will be weighted accordingly.
 You are not allowed (and will not need)
to use a calculator on midterms or finals.

You are allowed to bring a single 8x11 sheet of paper
containing
notes on both sides (formulas, whatever you find useful) to each midterm
and to the final. My view is that this allows you to focus on learning
how to do the problems and understanding the material, rather than
on memorizing formulas.

Hint for Midterms and Final:
The questions on all three exams should look very familiar.
I will make most of the problems on all three exams look very much like
the homework problems; in some cases, they will be exactly the same as some
of the homework problems, and in other cases, they will be minor
variations of homeworks.
(I will put at least one slightly more challenging problem on each
exam, which is not just a variation of a homework problem; this ensures
that everyone will have some challenge on the exam.)
LECTURES:
The lectures will follow the textbook quite closely;
however, I will not cover all sections in the book.
My lectures may sometimes expand a bit on a particular topic beyond
what is in that section of the book, if I think it is particularly
important or useful.
If I expect you to understand the material in a section and to be able
to work problems in that section, then I will give you at least one
homework problem from that section.
This means that you should have a look at the upcoming homework
assignment for the next two weeks to know what parts of the book
to read prior to the lectures.
Homework assignments will be a combination of theoretical and computer
problems; this will require some computer programming using MATLAB.
The TA will be able to help you with both the theoretical and computer
problems in both the discussions sections and by appointment.
