LameEigenvalueA

LameEigenvalueA[ν,j,m]

gives the ^(th) Lamé eigenvalue TemplateBox[{nu, j, m}, LameEigenvalueA] of order with elliptic parameter for the function LameC[ν,j,z,m].

Details

  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • The Lamé eigenvalue TemplateBox[{nu, j, m}, LameEigenvalueA] for successive gives the value of the parameter in the Lamé differential equation (where TemplateBox[{z, m}, JacobiSN] is the Jacobi elliptic function JacobiSN[z,m]), for which the solution is the function LameC[ν,j,z,m].
  • For certain special arguments, LameEigenvalueA automatically evaluates to exact values.
  • LameEigenvalueA[ν,j,0]=j2.
  • LameEigenvalueA can be evaluated to arbitrary numerical precision.
  • LameEigenvalueA automatically threads over lists.
