Note 1: You can read more details about the class from the syllabus.  There will be a weekly homework assignment. The homework will be anounced on this web page  below. You can find also the notes I use to teach in class below.  You can also find some past exams.

Note 2: This is a class in which programing is expected. I prefer that you program in MATLAB. MATLAB code will be given in class and can be found below.
