Ops.mvp: Arithmetic Ops Group Methods for mvp objects

Description

Allows arithmetic operators to be used for multivariate polynomials such as addition, multiplication, integer powers, etc.

Usage

# S3 method for mvp
Ops(e1, e2)
mvp_negative(S)
mvp_times_mvp(S1,S2)
mvp_times_scalar(S,x)
mvp_plus_mvp(S1,S2)
mvp_plus_numeric(S,x)
mvp_eq_mvp(S1,S2)

Arguments

e1,e2,S,S1,S2

Objects of class mvp

x

Scalar, length one numeric vector

Value

The high-level functions documented here return an object of mvp, the low-level functions documented at lowlevel.Rd return lists. But don't use the low-level functions.

Details

The function Ops.mvp() passes unary and binary arithmetic operators “+”, “-”, “*” and “^” to the appropriate specialist function.

The most interesting operator is “*”, which is passed to mvp_times_mvp(). I guess “+” is quite interesting too.

Examples

# NOT RUN {
p1 <- rmvp(3)
p2 <- rmvp(3)

p1*p2

p1+p2

p1^3


p1*(p1+p2) == p1^2+p1*p2  # should be TRUE

# }
