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 DCM convention are numerically stable. This conversion has no singularities. See the notes on rotation conventions for the basic definitions of rotations in Spinach.
