TransformationMatrix

TransformationMatrix[tfun]

gives the homogeneous matrix associated with a TransformationFunction object.

Details

  • For transformations in n dimensions, TransformationMatrix normally gives an × matrix.
  • mat[[1;;n,1;;n]] gives the linear part of the transformation; mat[[1;;n,-1]] gives the displacement vector.
