HankelH1[n, z]
gives the Hankel function of the first kind .
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • is given by J_n(z)+i​Y_n(z).
  • HankelH1[n, z] has a branch cut discontinuity in the complex z plane running from -∞ to 0.
  • For certain special arguments, HankelH1 automatically evaluates to exact values.
  • HankelH1 can be evaluated to arbitrary numerical precision.
  • HankelH1 automatically threads over lists.
