Topics on Final Exam
The final exam will take place Dec. 21, 7:00-9:00, WWH 312. If you are unable
to make this time, please let me know as soon as possible.
The exam will be closed book and closed notes. It will cover only subjects
that were discussed in lecture. The following will
NOT be on the exam.
- Minutiae of MATLAB. The MATLAB plotting functions.
- Gram-Schmidt orthogonalization algorithm
- Algorithm for inverting a matrix.
- Subjects discussed at the "makeup" lecture Wed. 11/18: Discrete Fourier
transform, eigenvalues and eigenvectors, singular value decomposition.
- Any questions that require any use of calculus.
- Any new subjects introduced in the last lecture 12/14.
My plan (subject to change) is that the exam will have two parts; a short
answer part of questions you should be able to answer quickly, and a number of
small (two or three line) MATLAB programming problems. I expect the MATLAB
code to be correct in spirit; I will not deduct points for trivial syntax
