Converts angle-axis rotation parameters into a directional cosine matrix.
Syntax
q=anax2dcm(rot_axis,rot_angle)
Arguments
rot_axis - cartesian direction vector given as a
row or column with three real elements
rot_angle - rotation angle in radians
Outputs
dcm - 3x3 directional cosine matrix
Notes
Both angle-axis and quaternion convention are numerically stable. This conversion has no singularities.
