anax2dcm.m

Converts angle-axis rotation parameters into a directional cosine matrix.

Syntax

dcm=anax2dcm(rot_axis,rot_angle)

Parameters

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.
