Exercises on change of basis; image compression
Problem 31.1: Verify that the vectors of the Haar wavelet basis, given in
lecture, are orthogonal. Adjust their lengths so that the resulting basis
vectors are orthonormal.
Problem 31.2: We can think of the set of all two by two matrices with
real valued entries as a vector space. Describe two different bases for this
space. Is one of your bases better than the other for describing diagonal
matrices? What about triangular matrices? Symmetric matrices?
