Thank you for answers.
Sorry for the long delay.
I couldn't solve the issue to calculate the Euler angles.
There are some points which make this item hard to solve for me.
One point is that some sets of Euler angles lead to one rotation matrix.
Another point is one entry of the rotation matrix represent the sin angle of one axis. But the value for 45° and 135° is the same for example.
I don't give up, may be I will found a solution in the future.
Greetings
Manfred
