All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class RepeatBlockMatrix
extends AllMatrices
implements java.lang.Cloneable, java.io.Serializable

This is a block (e.g. band) diagonal matrix where the block is the same each time it is repeated. The structure is like

     |---|                              or   |-------|
     | M ||---|                              |   M   | 
     |---|| M ||---|                         |-------|
          |---|| M | .                            |-------|
               |---|   .  |---|                   |   M   |
                          | M ||---|              |-------|
                          |---|| M |                     .
                               |---|                       .

The matrix M is repeated L times. Let M be of size N-by-K then for each repetition the matrix is translated K positions horisonotally and dN positions vertically or dK positions horisonotally and N positions vertically as illustrated above. That is dN==N or dK==K and 1 <= dN <= N and 1 <= dK <= K. The number of repetitions may be flexible, (L==0). The size (when L>0) of this matrix is (N+(L-1)*dN)-by-(K+(L-1)*dK).
