Public Class Methods

new(ring,ifunc=nil,jfunc=nil) click to toggle source

Constructor

ring must be a polynomial or multivariate power series ring. ifunc(ExpVector i) must return a value which is used in ((RingFactory)cofac).fromInteger(). jfunc(ExpVector i) must return a value of type ring.coFac.

# File examples/jas.rb, line 4914
def initialize(ring,ifunc=nil,jfunc=nil)
    super(ring);
    @coFac = ring.coFac;
    @ifunc = ifunc;
    @jfunc = jfunc;
end
