I have my SE3 object representing a 4x4 matrix. I need to extract the translation vector to get the [X Y Z] coordinates i.e. the values that are present at position (1,4) (2,4) (3,4) of the matrix represented by the object.

On the matlab documentation there are the various functions that the object can use. I followed the syntax but it doesn't recognize those functions either. Especially the function 'trvec' should solve my problem, but it doesn't work.
