Diffraction by a one‐dimensionally disordered crystal. III. Relation between the matrix and the probability tree methods

The calculation of the diffraction from a one-dimensionally disordered crystal is shown to be easier using the matrix (M) method than with the probability tree (PT) method. If the order of the difference equation is high, an analytical solution cannot be obtained by the PT method unless the model is highly simplified. There is no such limitation in the M method.
