HOMEWORK SUMMARY REPORT
Chapter number: 4
Section number: 5
Exercise number: 12
Number of papers received: 5
Reviewing committee: Kappa
List all participating committee members:
Brian Young, Randall McClelland
Author(s) of paper(s) chosen for publication:
Xujia Zhang
Comments: Mr. Zhangs paper was chosen because it was the only correct
solution. Though all of the papers were close to the correct solution,
many were misled by the solution online, which is incorrect. The paper is
sufficiently clear, and thus it was chosen to be published.
GRADER'S COMMENT: This is not a difficult problem. If B is the
coordinate transformation from b to natural and B' is the coordinate
transformation from b' to natural (both of which are transparent), and A
is the original matrix, the new matrix is B'^{-1}BAB^{-1}B'.
