This is great stuff. Concise and functional. However, I have a problem with function 'unitvector'. It is used in several places in the code but it is nowhere to be seen. Here's an example error message when trying to use 'OmegaAxis':
1492 [axis, omega] = unitvector( omegav, 1 );
Undefined function 'unitvector' for input arguments of type 'double'.
