- Usage:
`x = simpleDocFrob(n,M)`

- Function: simpleDocFrob
- Outputs:
`x`, a matrix, A block diagonal matrix with`n`copies of`M`along the diagonal

- Consequences:
The first side effect of the function, if any, is described here.

The second side effect of the function is described here, and so on.

Each paragraph of text begins with "Text". The following line starts a sequence of Macaulay2 example input lines. However, see `matrix(List)` (missing documentation).

The output in the following example was automatically generated at the time of package installation.

i1 : M = matrix"1,2;3,4"; 2 2 o1 : Matrix ZZ <--- ZZ |

i2 : simpleDocFrob(3,M) o2 = | 1 2 0 0 0 0 | | 3 4 0 0 0 0 | | 0 0 1 2 0 0 | | 0 0 3 4 0 0 | | 0 0 0 0 1 2 | | 0 0 0 0 3 4 | 6 6 o2 : Matrix ZZ <--- ZZ |

The following example was generated by the documentation author.

i1 : 4+ 4 o1 = 8 i1000 = 2+2 o1000 = 4 |
