Converts angle-axis rotation parameters into a directional cosine matrix.
Syntax
dcm=anax2dcm(rot_axis,rot_angle)
Arguments
rot_axis - cartesian direction vector given as
a row or column with three real ele-
ments
rot_angle - rotation angle in radians
Outputs
dcm - 3x3 directional cosine matrix
Notes
Both angle-axis and DCM convention are numerically stable. This conversion has no singularities. See the notes on rotation conventions for the basic definitions of rotations in Spinach.
