Determination of ν-zeros of Hankel functions

Title of program: NUZERO Catalogue Id: ACCH_v1_0 Nature of problem The nu-zeros of the equations: Hnu(1)(z) = 0, (d/dz)Hnu(1)(z) = 0, (d/dz)Hnu(1)(z) + iWHnu(1)(z) = 0, where Hnu(1)(z) is a Hankel function, are of interest in electromagnetic theory in numerous scattering and diffraction problems with circular or spherical boundaries.
