Mocking in C++

ACCU London's July 2011 talk was about mocking in C++, given by Ed Sykes and hosted by 7 City.

Ed talked about MockItNow and Hippomocks. He pointed out, as has been said many times before Mocks aren't Stubs.

I can no longer remember all the details so will have to try these out for myself to see how they work.

Many thanks to Ed for a great talk, though.

Power series for PCA

The book says estimate the value of the eigenvector, then iterate.
But my vector cycled as transpose(1,1), transpose(-1, 1), transpose(1, 1) which is a bit of a problem.
Oh for precise instructions.
I'll report back when I find a suitable estimate for the starting value.
