Homework problems

Due date



Final Exam: Thursday, December 14th, 2017, 7:309:30am, the same room as class. No calculators.
One page (two sides) of notes is allowed with definitions and algorithms only.
NO solutions of problems there! You will need to submit this page with your work.
What is covered: all topics.
You need to understand and be able to use definitions and algorithms.
Training set of problems:
Sauer, p. 19: 0.4.1;
Sauer, p. 59: 1.4.5;
Sauer, p. 101: 2.4.3;
Sauer, p. 198: 4.1.2, 4.1.79;
Sauer, p. 224: 4.3.1, 4.3.2 (Using both GrammSchmidt process and Givens' rotations (see lectures linalg45));
For linear algebra in general: you need to be able to estimate number of operations
necessary to complete the problem, understand sources of errors (condition number),
similar to problems in Midterm;
Sauer, p. 156: 3.2.13 (also work through problems in the Midterm);
Sauer, p. 164: 3.3.1, 3.3.5, 3.3.78;
Sauer, p. 176: 3.4.7, 3.4.12;
Sauer, p. 263: 5.2.13 (also you shall need understanding of error dependence on a grid step);
Sauer, p. 278: 5.5.13 (work through HW#11);
Sauer, p. 252: 5.1.1, 5.1.5;
Sauer, p. 321: 6.4.3 (you need to be able to use all methods we studied);
In all methods which we studied you need to understand
errors dependence on the parameters of methods like grid step etc.

Where to get MATLAB
Lecture 01 (matlab12)
explot.m Formats the plots in Matlab so they are easily viewable
on a smaller screen or when exported ("ex" stands for "export").

Lecture 02 (matlab12)
exsemilogy.m Analogous to explot.m, but provides larger semilogy format.
