4.22.1 vector declarations
- Syntax:
vector name = vector_expression ;
- Purpose:
- defines a vector of polynomials (an element of a free module).
- Default:
- [0]
- Example:
| ring r=0,(x,y,z),(c,dp);
poly s1 = x2;
poly s2 = y3;
poly s3 = z;
vector v = [s1, s2-s1, s3-s1]+ s1*gen(5);
// v is a vector in the free module of rank 5
v;
==> [x2,y3-x2,-x2+z,0,x2]
