Problem 3
Re-wording of the second question in part (c):
"Why might applying B be better
than applying a filter B’ that is filled with a full 3x3 set of
positive coefficients (e.g., changing the 0’s to 1’s in the B filter
given above), rather than just a single column of coefficients?"

Laid out the questions in part (c) as two bulleted questions to make it easier to read. (homework PDF updated on 4/24/2013)
Problem 4
Part (c) should start with:
"Now suppose you are given two vectors, a and b, each of arbitrary, non-zero length. We will also assume that these vectors are linearly independent, a ≠a b for any scalar value of a; i.e., the vectors don’t point in exactly the same or exactly opposite directions." (homework PDF updated on 4/24/2013)
At the end of part (c), added: "Note that there is more than one possible answer to this problem; you only need to provide one solution." (homework PDF updated on 4/24/2013)
Problem 6
Clarification for part (a): If two parts are connected physically, then they should be connected in the tree, as long as you don’t form a cycle by connecting them. (homework PDF updated on 4/24/2013)
