AlgError	AlgMatrixRSTDiag (AlgMatrix aMat, double *dVec, double *oVec)
	An implementation of Householder's alorithm which reduces a real aSz x aSz symmetric matrix to symmetric tridiagonal form by aSz - 2 orthogonal similarity transformations. This is a translation of the functions/subroutines 'tred2' in the fortran EISPACK library and the Numerical Recipies book, both of these are descended from the algol procedure tred2 in Wilkinson J.H and Reinsch C. Linear Algebra, Volume II Handbook for Automatic Computation. Springer-Verlag, 1971. See Numerical Recipies in C: The Art of Scientific Computing. Cambridge University Press, 1992. More...
