This is a very simple snippet, yet answers a commonly asked question.

## What is a Hilbert matrix?

A Hilbert matrix is a square matrix with unit fractions as entries. This is the equation for every cell of a Hilbert Matrix:

`H(i, j) = 1 / (i + j -1)`

Very simple! Great for testing matrix operations across the board, since the matrix for any size will always yield a consistent result.

## How do I create one?

Simply use the `hilb()`

function, passing in a matrix size into the function:

```
hilb(4)
1.0000 0.5000 0.3333 0.2500
0.5000 0.3333 0.2500 0.2000
0.3333 0.2500 0.2000 0.1667
0.2500 0.2000 0.1667 0.1429
```
