simpleDocFrob -- a sample documentation node

Synopsis

Usage:

x = simpleDocFrob(n,M)
Inputs:
- n, an integer, positive
- M, a matrix, which is square
Optional inputs:
- Limit => an integer, default value 0, sometimes useful
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.

Description

Each paragraph of text begins with "Text". The following line starts a sequence of Macaulay2 example input lines.

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

A new section

The following example was generated by the documentation author.

i1 : 4+
     4

o1 = 8

i1000 : 2+2

o1000 = 4

Inputs:
- an integer
- a matrix
Outputs:
- a matrix
Consequences:
- There may be specific consequences.

Paragraph specific to this usage. Itemized lists can be created with the "Tree" keyword:

A heading

matrix(List) -- create a matrix from a doubly-nested list of ring elements or matrices
A subheading containing Hypertext
- ZZ -- the class of all integers
- Matrix -- the class of all matrices

Another heading

A link with arbitrary headline.
