I share the MATLAB code that I wrote for symbolic calculations of the arbitrary reference frame transfer matrix. I hope you find it useful:
The code below will generate the transfer matrix to the arbitrary reference frame (Ks) for you (2:Kraus coefficients/1:Concordia coefficients):
(As you know: 2:magnitude-invariant transformation , 1: power-invariant transformation)
Now for example to calculate the term Ks.p(Ks-1) you can simply write simplify( Ks*diff(inv(Ks))) in the Command Window and your answer will be:
ans(t) =
[ 0, diff(theta(t), t), 0]
[ -diff(theta(t), t), 0, 0]
[ 0, 0, 0]
and by ω=diff(theta(t), t) we will have:
ans(t) =
[ 0, ω, 0]
[ -ω, 0, 0]
[ 0, 0, 0]
Have a nice time!
