D.9.2.5 texfactorize
Procedure from librarylatex.lib (see latex_lib).
- Usage:
- texfactorize(fname,f); fname string, f poly
- Return:
- if
fname="": string, f as a product of its irreducible factors
otherwise: append this string to the file<fname>, and return nothing. - Note:
- preceding ">>" are deleted and suffix ".tex" (if not given)
is added to
fname.
LIB "latex.lib";
ring r2 = 13,(x,y),dp;
poly f = (x+1+y)^2*x3y*(2x-2y)*y12;
texfactorize("",f);
==> $-2\cdot x^{3}\cdot y^{13}\cdot (x+y+1)^{2}\cdot (-x+y)$
ring R49 = (7,a),x,dp;
minpoly = a2+a+3;
poly f = (a24x5+x3)*a2x6*(x+1)^2;
f;
==> (a+3)*x13+(2a-1)*x12+(-2a+1)*x10+(-a-3)*x9
texfactorize("",f);
==> $(a+3)\cdot (x-1)\cdot (x+1)^{3}\cdot x^{9}$
