gives the angular spheroidal function of the second kind.


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • The angular spheroidal functions satisfy the differential equation with the spheroidal eigenvalue given by SpheroidalEigenvalue[n,m,γ].
  • SpheroidalQS[n,m,0,z] is equivalent to LegendreQ[n,m,z].
  • SpheroidalQS[n,m,a,γ,z] gives spheroidal functions of type . The types are specified as for LegendreP.
  • For certain special arguments, SpheroidalQS automatically evaluates to exact values.
  • SpheroidalQS can be evaluated to arbitrary numerical precision.
  • SpheroidalQS automatically threads over lists.
