Use MATLAB to complete the following questions. For questions that involve a set of vectors, enter each vector separately, giving it a name (e.g., s1 , s2 , s3 ) and then construct any required matrices from these vectors (e.g., A = [s1 s2 s3] ). This will make it easier for you to work with the various elements. Use the diary feature to record your work. Include a written conclusion for each part in your diary file as well. When finished, print out your diary file and submit it with the rest of your assignment.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
