5.1.124 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
