摘要:

We describe and compare the algorithms proposed by G. H. Golub and W. Kahan 1965 and by Ch. Reinsch 1967 to compute the Singular Value Decomposition. The current algorithm used in all software packages is the one of Reinsch. We explain this algorithms, analyze the details and program it. In the second part we discuss the ``Handbook of Automatic Computation'', the first attempt to built a software library. The algorithm of Reinsch has been accepted under joint authorship with G.H. Golub. If time permits, I will also demonstrate some applications of the SVD.
