<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>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: </p>
<pre class="fragment"> y = ones(d1,d2,...,dn).
</pre><p> The resulting array has the given dimensions, and is filled with all ones. The type of <code>y</code> is <code>float</code>, a 32-bit floating point array. To get arrays of other types, use the typecast functions (e.g., <code>uint8</code>, <code>int8</code>, etc.).</p>
<p>The second syntax specifies the array dimensions as a vector, where each element in the vector specifies a dimension length: </p>
<pre class="fragment"> y = ones([d1,d2,...,dn]).
</pre><p> This syntax is more convenient for calling <code>ones</code> using a variable for the argument. In both cases, specifying only one dimension results in a square matrix output. </p>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>The following examples demonstrate generation of some arrays of ones using the first form.</p>
<pre class="fragment">--> 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
</pre><p>The same expressions, using the second form.</p>
<pre class="fragment">--> ones([2,6])
ans =
1 1 1 1 1 1
1 1 1 1 1 1
--> ones([1,3])
ans =
1 1 1
</pre><p>Finally, an example of using the type casting function <code>uint16</code> to generate an array of 16-bit unsigned integers with a value of 1.</p>
<pre class="fragment">--> uint16(ones(3))
ans =
1 1 1
1 1 1
1 1 1
