The nentselp function returns a 4×4 transformation matrix, defined as follows:

The first three columns of the matrix specify scaling and rotation. The fourth column is a translation vector.

The functions that use a matrix of this type treat a point as a column vector of dimension 4. The point is expressed in homogeneous coordinates, where the fourth element of the point vector is a scale factor that is normally set to 1.0. The final row of the matrix, the vector [M 30 M 31 M 32 M 33 ], has the nominal value of [0 0 0 1]; it is currently ignored by the functions that use this matrix format.
