- 3/29/2010: For the quiz of Wednesday, March 31, I am
adding eigenvectors and eigenvalues to the definitions that you must
know.
For your convenience I have collected one version of these definitions
here.
- 3/21/2010: For the quiz of Wednesday, March 124, you must
know the definitions of:
- The span of a set of vectors (text, page 66);
- Linear independence of a set of vectors (text, page 76);
- A subspace of Rn (text, page 227).
- A basis of a subspace of Rn (text, page
241).
For your convenience I have collected one version of these definitions
here.
- 3/7/2010: On Wednesday, March 3, I announced that every quiz
in the future will ask you to give one definition. The question will
be worth two points and will be graded very strictly. Your definition must
be that of the book or class (not some equivalent notion); study the
definitions carefully in advance and be sure that you understand and can
reproduce them.
For the quiz of Wednesday, March 10, you must know the definitions of:
- The span of a set of vectors (text, page 66);
- Linear independence of a set of vectors (text, page 76);
- A subspace of Rn (text, page 227).
Definitions should be given in full sentences. Notice that :
- Span and
subspace are nouns and in fact denote sets of vectors; that
fact should be in the definition. For example, if asked for the definition
of a subspace you might begin "A subspace of
Rn is a subset W of
Rn such that . . ."
- Linearly independent is an adjectival phrase; a definition
might begin "A set of vectors is linearly independent if . . .".
- 3/7/2010: The original due date for MATLAB 3 was Monday, March
8. Because I announced that I might change this, but never posted a new
due date, I will accept MATLAB Assignment 3 on Wednesday, March 10.
However, due dates for future MATLAB assignments will be those of the
original syllabus.
- 2/9/2010: Changes in class schedule due to class cancellation
Wednesday, February 10:
- My office hours are also canceled Wednesday 2/10.
- The quiz we would have had on February 10 is canceled. Our
next quiz will be Wednesday, February 17.
- The due date for MATLAB assignment 2 is now Wednesday, February
17. This lab uses matrix multiplication, which we just began to discuss
on Monday. It does not use very much about it, and you could really do the
lab without another class, but since we will be talking more about matrix
algebra on Monday it seems best to give you some extra time. Due dates
of future MATLAB assignments may or may not be altered; I will announce
these due dates as appropriate.
- On Monday, February 15, we will finish section 2.1 and begin section
2.2. In general I hope to move a little faster than our syllabus for a
while and perhaps make up the lost day before the end of the semester.
- 2/8/2010: Here are hints from our
MATLAB grader for future MATLAB write-ups.
- 1/31/2010: Here are the promised class
notes showing two Gaussian elimination procedures, from the lecture of
January 27.
