MATLAB: How to convert Euler angles to axis-angle vectors using the blocks of the Aerospace Blockset

Question

I am trying to convert Euler angles to axis-angle vectors but I have only been able to find the Euler to Quaternion block in the Aerospace Blockset.

Answer 1

There is no block that implements the transformation from Euler angle to Axis-Angle vector. However, this can be implemented as a workaround in an Embedded MATLAB function block as shown in the attached model file.

The transformation is available at the following URL:
