com.singularsys.extensions.polynomials.ComplexPolynomialRewriter

public class ComplexPolynomialRewriter
extends AbstrctPolynomialRewriter

Rewrites polynomials with powers of i, the square root of -1, to a form without i. For example, x + 3 i x + 5 i^2 x + 7 i^3 x is rewritten to (-4*i*x-3*x.

Description copied from class: AbstrctPolynomialRewriter

Rewrite a mutable monomial. The default implementation simply returns mm.toNode() creating new monomial with the same coefficient, variables and powers.

Overrides:

rewrite in class AbstrctPolynomialRewriter

Parameters:

mm - the mutable monomial to rewrite

Returns:

a new monomial

Throws:

ParseException
