gives the value of the discrete logarithm of e.
更多信息和选项
- To use FieldInd, you first need to load the Finite Fields Package using Needs["FiniteFields`"].
- With p a primitive element of the field associated with the element e, the value of the discrete logarithm of e is the integer n such that pne.
- FieldInd is defined only if PowerListQ has been set True for the field.
- FieldInd[0] gives -∞.
