Course Syllabus

Getting Help

Getting good help can sometimes be frustrating. I am trying to make my self available by choosing varied office hours and being available by email. My email response time varies a lot so asking questions early is your best strategy. Sometimes you may have a complex question that would benefit by including a picture in email. This is fine, but please use reduced-size photos -- typically a 250kB picture is sufficient, while a 5MB picture can really bog down email.

Course Notes

  • Example script file which explains how to use Octave to solve a mixed-integer optimization problem. This file also can be executed by Octave so it serves as a template for problems which you may wish to solve. And here is the Matlab version.

I found a few recent midterm exams for you to use as study and practice material. Remember that the specifics of your midterm exam is relative to the course content this semester, so not all questions in these examples may be relevant. I will be happy to answer any questions you may have about these exam questions provided that you show me a significant effort at a solution and discuss your work with me. Here are the practice exams: PracticeExam1,PracticeExam2, PracticeExam3.

Here are some sample exercise solutions from chapters 6 and 7. Keep in mind that lengthy answers are not necessarily better answers. Consider the brevity of my solutions and their focus on the current linear algebra concepts. And here are two more example proofs. And, here are two examples of how to show if a transformation is linear or not.
