Matlab will be the main computational tool for both the homework and the project. Note that per the following university guidelines, the instructor will set the policy for late assignments (See

A quiz will be administered to the class. The quiz will be after completion of the core concepts of system analysis. Only the University approved reasons will be accepted for missing a quiz (See A make-up quiz will be administered at the mutual convenience of the student and the Instructor. In all cases, signed documentation must be provided to the Instructor and attached to the make up quiz in order to obtain credit.

Class Project
Each student will implement the analysis method to be assigned for the project as computer program. The student will prepare a written report and submit it with the computer code.
