Kahan is one of the great numerical analysts of our time. This was an application of earlier algorithmic work published by Wilkinson for the symmetric eigenvalue decomposition. It was important work because it allowed for achieving better accuracy of the smaller singular values. But lots of work is now available that improves this accuracy.

If you also post its used in information retrieval in the process of latent semantic indexing it will be very helpful for me. Thank you again for the post. very interesting and informative.

It is really nice! Unfortunately second part is still in my folder with unfinished stuff... but I promise I will invest some time to finish it and ping you as soon as it is available. Once again... thank you for a kind words! Thank you for a feedback. It is really nice!

Is there a second part somewhere - I want more of this sort of stuff? Thanks for putting this together! This was brilliant. Is there a second part somewhere - I want more of this sort of stuff?

In order to produce images of matrix operations I use MathType. I also use Omni Graffle to add comments to images exported from MathType. Thank you very much.

I enjoyed your blog post and I'm looking forward to your subsequent ones. Incidentally, how did you produce your images of matrix operations (they are beautiful)? No worries.
