Algorithm (Workflow)
This function, rotdeg, computes a 3x3 rotation matrix for given rotation angles in degrees around the x, y, and z axes. It is part of the SG-Library and was developed by Tim Lueth.
Input Parameters
- wx: Angle for rotation around the x-axis in degrees.
- varargin: Optional parameters for angles around the y-axis and z-axis in degrees.
Output
- R: A 3x3 rotation matrix.
Algorithm Explanation
The function begins by defining a conversion factor f to convert degrees to radians, which is pi/180.
The function checks the number of input arguments using nargin:
- If there is only one input argument (
nargin==1), it assumes a single rotation around the x-axis. It converts wx from degrees to radians by multiplying with f and calls the rot function with this value.
- If there are more than one input arguments, it assumes rotations around all three axes. It converts
wx, varargin{1} (which is wy), and varargin{2} (which is wz) from degrees to radians by multiplying each with f. It then calls the rot function with these three values.
The function relies on an external function rot to compute the actual rotation matrix from the given angles in radians.
