tr2rpy

Convert a homogeneous transform to roll-pitch-yaw angles

rpy = tr2rpy(T, options) are the roll-pitch-yaw angles (1x3) corresponding to the rotation part of a homogeneous transform T. The 3 angles rpy=[R,P,Y] correspond to sequential rotations about the X, Y and Z axes respectively.

rpy = tr2rpy(R, options) as above but the input is an orthonormal rotation matrix R (3x3).

If R (3x3xK) or T (4x4xK) represent a sequence then each row of rpy corresponds to a step of the sequence.

Options

'deg' Compute angles in degrees (radians default)
'zyx' Return solution for sequential rotations about Z, Y, X axes (Paul book)
