• R : Ring

Computes all the symmetric functions in n variables.

symFunc : (R, PositiveInteger) -> Vector(R)

symFunc(r, n) returns the vector of the elementary symmetric functions in [r, r, ..., r] n times.

symFunc : List(R) -> Vector(R)

symFunc([r1, ..., rn]) returns the vector of the elementary symmetric functions in the ri's: [r1 + ... + rn, r1 r2 + ... + r(n-1) rn, ..., r1 r2 ... rn].
