vectorToMonomial -- Converts an exponent vector into a monomial.

Synopsis

Usage:

vectorToMonomial(v,R)
Inputs:
- v, a vector
- R, a polynomial ring
Outputs:
- a ring element

Description

Converts the exponent vector v into a monomial in the variables of R. The number of variables of R has to match the length of v.
