You might want to look at this link -
https://galgebra.readthedocs.io/en/latest/
Also if you could show me symbolically (not code) what you are doing
perhaps I could give you an example of how to do it in galgebra.

which uses Matrix() as a workaround to create a vector. The author
says, that it can not be transformed between coordinate systems, like
real vectors, though.
I need to transform my input and output vector from one coordinate
system to another (and back). How are vector functions done in that
case? My function is simple:
def B_el(r_vec, I):
mu_0 = 4 * np.pi * 1e-7
a1 = -0.05
a2 = 0.0
C = mu_0 * I / np.pi
r1 = r_vec.i
r2 = r_vec.j
u = (2 * C * r2 * (a1 * r1 + a2 * r2)) / np.square(r1*r1 + r2*r2) - (C
* a2) / (r1*r1 + r2*r2)
v = (C * a1) / (r1*r1 + r2*r2) - (2 * C * r1 * (a1 * r1 + a2 * r2)) /
np.square(r1*r1 + r2*r2)
return Matrix([u, v, 0])
