Please answer the following questions.
- (10%) Individual:
An orthogonal matrix is one whose inverse is equal to
its transpose. So, if A is an orthogonal matrix and AT its
transpose,
then A * AT is the identity matrix.
Do the following:
- Come up with an orthogonal matrix A (you may not use the identity matrix)
- Calculate it's transpose AT
- Use your program from last week to show A*AT is the identity matrix.
- (90%) Group:
Turn in:
Email Somchaya Liemhetcharat:
- The output of the program run for part 1 (showing the input
matrices and the result).
- The URL for part 2 (webpage of the Rube Goldberg lab).
(If you submitted a hard copy at the beginning of class on Wednesday, 1/21, then you only need to email the URL.)
