Modulus

Modulusn

is an option that can be given in certain algebraic functions to specify that integers should be treated modulo n.

Details

  • Modulus appears as an option in Solve, Reduce, Factor, PolynomialGCD, and PolynomialLCM, as well as in linear algebra functions such as Inverse, LinearSolve, and Det.
  • Arithmetic is usually done over the full ring of integers; setting the option Modulus specifies that arithmetic should instead be done in the finite ring .
  • The setting Modulus->0 specifies the full ring of integers.
  • Some functions require that Modulus be set to a prime, or a power of a prime. is a finite field when is prime.
  • Equations for Modulus can be given in Eliminate and related functions.
