4.13.1 module declarations
- Syntax:
module name = list_of_vector_expressions ;
module name = module_expression ;
- Purpose:
- defines a module.
- Default:
- [0]
- Example:
| ring r=0,(x,y,z),(c,dp);
vector s1 = [x2,y3,z];
vector s2 = [xy,1,0];
vector s3 = [0,x2-y2,z];
poly f = xyz;
module m = s1, s2-s1,f*(s3-s1);
m;
==> m[1]=[x2,y3,z]
==> m[2]=[-x2+xy,-y3+1,-z]
==> m[3]=[-x3yz,-xy4z+x3yz-xy3z]
// show m in matrix format (columns generate m)
print(m);
==> x2,-x2+xy,-x3yz,
==> y3,-y3+1, -xy4z+x3yz-xy3z,
==> z, -z, 0
