gives the modular lambda elliptic function .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • ModularLambda is defined only in the upper half of the complex plane. It is not defined for real .
  • The argument is the ratio of Weierstrass halfperiods .
  • ModularLambda gives the parameter for elliptic functions in terms of according to .
  • ModularLambda is related to EllipticTheta by where the nome is given by .
  • is invariant under any combination of the modular transformations and . »
  • For certain special arguments, ModularLambda automatically evaluates to exact values.
  • ModularLambda can be evaluated to arbitrary numerical precision.
  • ModularLambda automatically threads over lists.
