For calculating with SO3Fun (+, -, .*, ./, conv, ...) we have to verify that the symmetries are suitable.
By default the Left and Right symmetries of both functions have to coincide. By convolution of SO3Fun's the Left symmetry of one function have to coincide with the right symmetry of the other function.
Evaluation of some SO3Fun in some orientation also needs suitable symmetries.
|msg||yields a error message if the symmetry do not match|
|conv||be shure switched symmetries match|
