MATLAB Assignment
Due: Friday, Nov 30, 2018


1. Let A be the matrix
  [ 2  7 -3 ]
  [ 10 6  5 ]
Use MATLAB to compute the following:

(a) B = A transpose (remember MATLAB uses single quote for transpose instead of a little t)

(b) A * B

(c) (A * B) inverse (that's ^-1 in MATLAB)

(d) The determinant of (B * A) (that's det in MATLAB). Also compute the determinant of (B * A) "by hand" using the trick for 3 by 3 matrices (you might want to use MATLAB to help with the arithmetic).

(e) Does it make sense to compute the inverse of B * A ? What happens when you try?

2. Do Exercise #2 on p.268. Modify the LiveScript document section4_6.mlx (on the class website) to show your answers are correct.

3. Do Exercise #6 on p.269. Modify the LiveScript document section4_6.mlx (on the class website) to show your answers are correct.
