Real and imaginary manipulation

Get or set real and imaginary components of brobs or glubs.

Usage

# S4 method for class 'glub'
Re(z)
# S4 method for class 'glub'
Im(z)
# S4 method for class 'glub'
Mod(z)
# S4 method for class 'glub'
Conj(z)
# S4 method for class 'glub'
Arg(z)
Re(z) <- value
Im(z) <- value

Arguments

z

object of class glub (or, in the case of Im<-() or Im(z) <- value, class brob)

value

object of class numeric or brob

Value

Functions Re() and Im() return an object of class brob; functions Re<-() and Im<-() return an object of class glub
