Assessment 
Your grade in this course will depend on your performance on two written inclass midterm exams, weekly quizzes given during recitation sessions and a comprehensive final. Tentative weight of assessment components:
 Midterm I (March 3, in class): 25%
 Midterm II (April 21, in class): 25%
 Final exam (Thurs. May 12, 10:30 am1:15 pm): 25%
 Quizzes: 15%
 Participation: 10%
Letter grade will be determined as follows:
Score above
 90%
 80%
 70%
 60%
 otherwise
 Letter grade
 A
 B
 C
 D
 F

Weekly practice problems will be given that will not count towards the final grade, unless specifically noted. I strongly encourage all participants to do these exercises in order to gain the necessary grasp of the material and perform well on exams and graded assingments. I will discuss solutions in class every week.
I expect all class participants to abide to the rules and regulations specified in the official
GMU Honor code.

About MATLAB

MATLAB is an interactive programming language for general scientific and technical computation with powerful graphics and library functions.
We will be using MATLAB environment for some homework problems towards the end of the semester and I expect you to be able to get access to it. Here is some relevant information.
 Some guidelines for accessing and using MATLAB are available here: http://math.gmu.edu/introtomatlab.htm
 A standalone student version of the product is available from
Mathworks website for a reasonable price.
Some MATLAB tutorials you might want to read:

Useful links

Every now and then I find interesting information on the web or in press.
I'll be putting this stuff here, since it could help some of you to refresh things you might have forgotten or
to aid with the general understanding of the course.
If you find something useful yourself, please let me know,
I'll be really happy to expand this list with your suggestions.
