Coercion from numeric to Clifford form

pseudoscalar.Rd

Given a numeric value or vector, return a Clifford algebra element

Usage

pseudoscalar()
is.pseudoscalar(C)

Arguments

C

Object possibly of class Clifford

Details

Function pseudoscalar() returns the unit pseudoscalar of dimensionality option("maxdim") and function is.pseudoscalar() checks for a Clifford object being a pseudoscalar. Note that these functions require maxdim to be set; otherwise they are meaningless.

Usually, one will set option(maxdim) at the start of a session, together with the signature. Then one might define I <- pseudoscalar() in the interests of compactness and legibility.
