5.1.122 qhweight
Syntax:
qhweight ( ideal_expression )
Type:
- intvec
Purpose:
- computes the weight vector of the variables for a quasihomogeneous ideal.
If the input is not weighted homogeneous, an intvec of zeros is returned.
Example:
| ring h1=32003,(t,x,y,z),dp;
ideal i=x4+y3+z2;
qhweight(i);
==> 0,3,4,6
