We present a FORTRAN implementation of a divide-and-conquer method for computing the spectral resolution of a unitary upper Hessenberg matrix __H__ . Any such matrix __H__ of order __n__ , normalized so that its subdiagonal elements are nonnegative, can be written as a product of __n__ -1\* Givens m
