BLOCK Function |
The BLOCK function forms a block-diagonal matrix. The blocks are defined by the arguments to the function. Up to 15 matrices can be specified. The matrices are combined diagonally to form a new matrix.
For example, if , , and are any matrices, then the block matrix formed from these matrices has the following form:
The following statements produce a block-diagonal matrix composed of three blocks, shown in Figure 23.44:
a = 1; b = {2 2, 3 3}; c = {4 4 4, 5 5 5}; d = block(a, b, c); print d;
