D.9.2.9 texpoly
Procedure from library latex.lib (see latex_lib).
- Usage:
- texpoly(fname,p); fname string, p poly
- Return:
- if
fname="": string, the polynomial p in LaTeX-typesetting;
otherwise: append this string to the file <fname>, and
return nothing.
- Note:
- preceding ">>" are deleted in
fname, and suffix ".tex"
(if not given) is added to fname.
Example:
| | LIB "latex.lib";
ring r0=0,(x,y,z),dp;
poly f = -1x^2 + 2;
texpoly("",f);
==> $-x^{2}+2$
ring rr= real,(x,y,z),dp;
texpoly("",2x2y23z);
==> $2.000x^{2}y^{23}z$
ring r7= 7,(x,y,z),dp;
poly f = 2x2y23z;
texpoly("",f);
==> $2x^{2}y^{23}z$
ring rab =(0,a,b),(x,y,z),dp;
poly f = (-2a2 +b3 -2)/a * x2y4z5 + (a2+1)*x + a+1;
f;
==> (-2a2+b3-2)/(a)*x2y4z5+(a2+1)*x+(a+1)
texpoly("",f);
==> $-\frac{2a^{2}-b^{3}+2}{a}\cdot x^{2}y^{4}z^{5}+(a^{2}+1)\cdot x+(a+1)$
texpoly("",1/(a2+2)*x2+2/b*x+(a+1)/3);
==> $\frac{1}{a^{2}+2}\cdot x^{2}+\frac{2}{b}\cdot x+\frac{a+1}{3}$
