Function: gfactor (<expr>) Factors the polynomial <expr> over the Gaussian integers (that is, the integers with the imaginary unit
%i adjoined). This is like
factor (<expr>, <a>^2+1) where <a> is
(%i1) gfactor (x^4 - 1); (%o1) (x - 1) (x + 1) (x - %i) (x + %i)
There are also some inexact matches for
?? gfactor to see them.
