Moreover, when these functions are define dover integers, we prove that the bidiagonal factorization can be computed with high relative accuracy and so we can compute with high relative accuracy their eigenvalues,singular values,inverses and the solutions of some associated linear systems. We provide numerical examples illustrating this high relative accuracy.
