<p>vtable1k —
Read a vector (several scalars simultaneously) from a table.

<div class="refsect1">
<a id="idm281472870213176"></a>
<h2>Description</h2>
<p>
This opcode reads vectors from tables at k-rate.
</p>
</div>
<div class="refsect1">
<a id="idm281472870131624"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>vtable1k</strong></span> kfn,kout1 [, kout2, kout3, .... , koutN ]</pre>
</div>
<div class="refsect1">
<a id="idm281472870129112"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>kfn</em></span> - table number
</p>
<p>
<span class="emphasis"><em>kout1...koutN</em></span> - output vector elements
</p>
<p>
<span class="emphasis"><em>vtable1k</em></span> is a reduced version of <a class="link" href="vtablek.html" title="vtablek"><em class="citetitle">vtablek</em></a>, it only allows to access the first vector (it is equivalent to vtablek with kndx = zero, but a bit faster). It is useful to easily and quickly convert a set of values stored in a table into a set of k-rate variables to be used in normal opocodes, instead of using individual <a class="link" href="table.html" title="table"><em class="citetitle">table</em></a> opcodes for each value.
