HomogenousMatrixQ

HomogenousMatrixQ[m]
returns True if m is a list of lists with {4, 4} dimension with the last row is {0, 0, 0, 1} that formally can represent a homogeneous matrix, and gives False otherwise.
  • The HomogenousMatrixQ function does not check whether the rotation matrix is orthonormal.
  • The elements of the first three row can be any expression containing variables.
