My Solutions to
Professor Neu's Rehersal Problem, (please also look at
Midterm 2 and my
scribbled notes on how to do the problems. If anyone finds errors please let
me know, or if any of my steps are confusing, please let me know and I'll provide more detail.
If there's anything in particular you'd like me to write up, please email me. The following lists when I will
Notes and Codes:
be available over the next week, (for info on Jianlin and Soorosh, see their websites).
May 15-->Patch Office Hours, 1-4pm, 2165 Etcheverry Hall.
May 17-->Patch Office Hours, 11am-1pm, 2165 Etcheverry Hall.
May 18-->FINAL EXAM, 8am, 4 Leconte Hall. Bring a bluebook, a calculator, and notes on one side of one piece of paper.
Good Luck on all your exams!!
Jianlin has written up some Notes on Drawing Phase Planes.
linearODE.m is a short MATLAB code for visualizing ODE solutions.
Trapezoidal Rule Error derivation, (even powers of h).
This will NOT be on any quiz or test, but perhaps some of you will find it interesting. Thanks very much to Will Felder
for finding some typos, (which I've corrected). If anyone finds more typos, please let me know.
Polynomial Interpolation Error Formulas,
Proof Outlines, and notes on
Constructing the Interpolating Polynomials.
quiz 2 solutions, as well as a
concept from my approach to the second part of problem 1.
least squares notes, examples, and comments.
natural cubic splines derived differently than in lecture. (Don't use these to do Lab 5!!)
convergence rates of sequences, including why the secant
method converges with order (1+sqrt(5))/2.
significant digits in fixed point iterations.
accelerating the convergence of fixed point iterations.
Very soon I will write up a discussion about the stability of fixed points at which |g'|=1.
logistic.m is a Matlab code for generating the logistic map.
fixedpt.m is a Matlab code for generating fixed point iteration step diagrams.

Lecture Notes from an old version of Math128a are
My ME175 site. ME175 is about Lagrangian dynamics- think particles sliding over crazy
surfaces, and satellites tumbling through space. I'll be posting codes at this site that demonstrate
how to solve ODEs in Matlab, and more importantly how to interpret (i.e., visualize) ODE solutions.
Mastering Matlab is a comprehensive, well written, and well illustrated Matlab bible. I highly
recommend this book! Copies are available at Cody's on Telegraph, (3 blocks from campus).
Matlab Online Help. This is the
official Matlab website. It appears to contain a "getting started"
tutorial for using Matlab. Also, it provides the help documentation for any Matlab function.
