minus

is.minus

Very simple function that takes the negative of a vector, here so that
idiom such as
<code>coeffs(z)[gradesminus(z)%%2 != 0] %&lt;&gt;% minus</code>
works as intended (this taken from <code>Conj.clifford()</code>).

A suite of routines for Clifford algebras, using the
'Map' class of the Standard Template Library.  Canonical
reference: Hestenes (1987, ISBN 90-277-1673-0, "Clifford algebra
to geometric calculus").  Special cases including Lorentz transforms,
quaternion multiplication, and Grassman algebra, are discussed.
Conformal geometric algebra theory is implemented.  Uses 'disordR'
discipline.
