D.15.22.3 jordanVecField
Procedure from library VecField.lib (see VecField_lib).
- Usage:
- jordanVecField(VecField V)
- Return:
- new vecfield W in coordinates s.t. W.lin is in Jordan normal
form.
- Assume:
- eigenvalues of V.lin in basefield.
Example:
| LIB "VecField.lib";
ring r = 0, (x, y, z),ds;
vector v = [-1,-1,-1];
VecField V = v;
V.precision = 4;
map phi = r, x-2y2+z3,2y+y3+z,z;
VecField W = changeCoordinates(V,phi);
VecField X = jordanVecField(W);
