    • I graded the exams, then
    • weighted the problem you thought easiest to hardest using the following weight vector: W=(1.75,1.45,1.15, .85, .6, .25)

• Let's make the 5.2. homework due next time.

• On the project:
  • begin with the matrix operations, before you get to the image analysis. You should find ways to carry out the matrix operations.
