PK_matrix_type_t

typedef int PK_matrix_type_t;

Used in:

PK_TRANSF_classify_r_t

This datatype is used to classify the components of the upper left
3 X 3 submatrix. The possible values it can take are:

    PK_matrix_type_identity_c     the identity matrix.

    PK_matrix_type_rotation_c     a rotation matrix.

    PK_matrix_type_reflection_c   an orthonormal matrix that includes a
                                  reflection.

    PK_matrix_type_general_c      the value in all other cases.

    PK_matrix_type_unclassified_c used only if classification cannot be
                                  determined.
