Anisotropic part of the Hamiltonian for a specific spin system orientation.
Syntax
H=orientation(Q,euler_angles)
Arguments
Q - rotational basis as returned by
hamiltonian.m function
euler_angles - a 1x3 vector specifying Euler
angles (radians) relative to the
input orientation
Outputs
H - anisotropic part of the Hamiltonian
for the specified Euler angles
Note: this function may be used in both Hilbert and Liouville
space because the H -> [H, ] adjoint map is linear.
TODO: efficient sparse summation.

Notes
This function may be used in both Hilbert and Liouville space because the H -> [H, ] adjoint map is linear.
