I'm a physics Ph.D in Australia. This stuff is pretty everyday for me, Indeed I've laready done the calculation. Happy to write up the full solutions as you like.
I have passed some related courses (including pattern recognition) and implemented a couple of projects on dimensionality reduction (esp. PCA, LDA, ...).
I have a PhD degree in theoretical and computational physics. SVD and related methods of matrix analysis are my daily bread. I work in Matlab all the time. It would be my pleasure to solve this problem.
