CSE 3380 – Homework #3 Assigned: Monday, February 8, 2016 Due: Monday, February 15, 2016 at 3:50pm (the end of class) Note the following about the homework: 1. You must show your work to receive credit. 2. If your submission has more than one page, staple the pages. Assignment: Process 1. For each set of partitioned matrices below, find AB using multiplication of partitioned ma- trices. The partitions to use are given. a ) A = 1 2 3 4 5 6 7 8 0 1 0 2 3 0 4 0 , B = 1 2 3 4 1 3 2 4 , b ) A = 1 2 3 4 5 6 7 8 0 1 0 2 3 0 4 0 , B = 1 2 3 4 1 3 2 4 2. Find the determinants of the following: a ) A = bracketleftbigg 1 3 - 2 - 6 bracketrightbigg , b ) A = 1 2 0 3 0 1 0 1 4 , c ) A = 1 0 0 0 2 0 0 3 0 0 0 4 0 0 0 0 0 0 0 5 0 0 0 6 0 , d ) A = 1 2 3 4 5 0 1 6 6 - 3 0 0 1 9 10 - 2 - 4 - 6 - 7 1 0 3 18 18 - 8 Theory For each of the following, use the rules of matrix algebra to show that the relationship is true. Don’t replace the matrices by matrices with actual numbers nor generic matrices in which you use dot products to perform the multiplication. You should be able to show these using the representation of a matrix by a single letter, which is one of the strengths of the matrix representation of the relationships between values. 3. If A,B R n × n , show that A ( B - 1 ( A + B ) A - 1 ) B = A + B 4. If A R m × n , B R n × p , C R p × q , and D R q × t , show that ( ABCD ) T = D T C T B T A T

### 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.
