<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>Creates an array of zeros 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 = zeros(d1,d2,...,dn).
</pre><p> The resulting array has the given dimensions, and is filled with all zeros. The type of <code>y</code> is <code>double</code>, a 64-bit floating point array. To get arrays of other types, use the typecast functions (e.g., <code>uint8</code>, <code>int8</code>, etc.). An alternative syntax is to use the following notation: </p>
<pre class="fragment"> y = zeros(d1,d2,...,dn,classname)
</pre><p> where <code>classname</code> is one of 'double', 'single', 'int8', 'uint8', 'int16', 'uint16', 'int32', 'uint32', 'int64', 'uint64', 'float', 'logical'.</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 = zeros([d1,d2,...,dn]),
</pre><p> or </p>
<pre class="fragment"> y = zeros([d1,d2,...,dn],classname).
</pre><p> This syntax is more convenient for calling <code>zeros</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 zero arrays using the first form.</p>
<pre class="fragment">--> zeros(2,3,2)
ans =
(:,:,1) =
0 0 0
0 0 0
(:,:,2) =
0 0 0
0 0 0
--> zeros(1,3)
ans =
0 0 0
</pre><p>The same expressions, using the second form.</p>
<pre class="fragment">--> zeros([2,6])
ans =
0 0 0 0 0 0
0 0 0 0 0 0
--> zeros([1,3])
ans =
0 0 0
</pre><p>Finally, an example of using the type casting function <code>uint16</code> to generate an array of 16-bit unsigned integers with zero values.</p>
<pre class="fragment">--> uint16(zeros(3))
ans =
0 0 0
0 0 0
0 0 0
</pre><p>Here we use the second syntax where the class of the output is specified explicitly</p>
<pre class="fragment">--> zeros(3,'int16')
ans =
0 0 0
0 0 0
0 0 0
