7.2.4.1 poly declarations (plural)

Syntax:
poly name = poly_expression ;

Purpose:
defines a polynomial.

Default:
0

Example:
 
ring r = 32003,(x,y,z),dp;
def R=nc_algebra(-1,1);
setring R;
// ring of some differential-like operators
R;
==> // coefficients: ZZ/32003
==> // number of vars : 3
==> //        block   1 : ordering dp
==> //                  : names    x y z
==> //        block   2 : ordering C
==> // noncommutative relations:
==> //    yx=-xy+1
==> //    zx=-xz+1
==> //    zy=-yz+1
yx;      // not correct input
==> xy
y*x;     // correct input
==> -xy+1
poly s1  = x3y2+151x5y+186xy6+169y9;
poly s2  = 1*x^2*y^2*z^2+3z8;
poly s3  = 5/4x4y2+4/5*x*y^5+2x2y2z3+y7+11x10;
int a,b,c,t=37,5,4,1;
poly f=3*x^a+x*y^(b+c)+t*x^a*y^b*z^c;
f;
==> x37y5z4+3x37+xy9
short = 0;
f;
==> x^37*y^5*z^4+3*x^37+x*y^9
