|  |  D.6.16.7 relweight Procedure from libraryspcurve.lib(see  spcurve_lib).
 
Example:Usage:
relweight(N,W,a); N matrix, W intmat, a intvec
Assume:
N is a non-zero matrix
W is an integer matrix of the same size as N
 a is an integer vector giving the weights of the variables
 
Return:
integer, max(a-weighted order(N_ij) - W_ij | all entries ij) string "ERROR" if sizes do not match
 
 |  | LIB "spcurve.lib";
ring r=32003,(x,y,z),ds;
matrix N[2][3]=z,0,y,x,x^3,y;
intmat W[2][3]=1,1,1,1,1,1;
intvec a=1,1,1;
relweight(N,W,a);
==> 2
