D.15.26.3 jordanVecField
Procedure from libraryVecField.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.
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); |
