## ONES Array of Ones

### Usage

Creates an array of ones of the specified size. Two seperate syntaxes are possible. The first syntax specifies the array dimensions as a sequence of scalar dimensions:
```   y = ones(d1,d2,...,dn).
```

The resulting array has the given dimensions, and is filled with all ones. The type of `y` is `float`, a 32-bit floating point array. To get arrays of other types, use the typecast functions (e.g., `uint8`, `int8`, etc.). The second syntax specifies the array dimensions as a vector, where each element in the vector specifies a dimension length:

```   y = ones([d1,d2,...,dn]).
```

This syntax is more convenient for calling `ones` using a variable for the argument. In both cases, specifying only one dimension results in a square matrix output.

### Example

The following examples demonstrate generation of some arrays of ones using the first form.
```--> ones(2,3,2)

ans =

(:,:,1) =
1 1 1
1 1 1

(:,:,2) =
1 1 1
1 1 1

--> ones(1,3)

ans =
1 1 1
```

The same expressions, using the second form.

```--> ones([2,6])

ans =
1 1 1 1 1 1
1 1 1 1 1 1

--> ones([1,3])

ans =
1 1 1
```

Finally, an example of using the type casting function `uint16` to generate an array of 16-bit unsigned integers with a value of 1.

```--> uint16(ones(3))

ans =
1 1 1
1 1 1
1 1 1
```
