<h2>Description</h2>
<p>
This opcode writes vectors to tables at init time.

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>vtablewi</strong></span> indx, ifn, ixmode, inarg1 [, inarg2, inarg3 , .... , inargN ]</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp53395608"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>indx</em></span> - Index into f-table, either a positive number range matching the table length (<span class="emphasis"><em>ixmode</em></span> = 0) or a 0 to 1 range (<span class="emphasis"><em>ixmode</em></span> != 0).
</p>
<p>
<span class="emphasis"><em>ifn</em></span> - table number
</p>
<p><span class="emphasis"><em>ixmode</em></span> - index data mode. The default value is 0.</p>
<p> == 0 index is treated as a raw table location,</p>
<p> == 1 index is normalized (0 to 1).</p>
<p>
<span class="emphasis"><em>inarg1...inargN</em></span> - input vector elements
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp53398640"></a>
<h2>Performance</h2>
<p>
This opcode is useful in all cases in which one needs to write sets of values associated to unique indexes (for example, multi-channel samples, STFT bin frames, spectral formants, p-field based scores etc.). The number of elements of each vector (length of the vector) is determined by the number of optional arguments on the right (<span class="emphasis"><em>inarg1</em></span>, <span class="emphasis"><em>inarg2</em></span>, <span class="emphasis"><em>inarg3</em></span>, .... <span class="emphasis"><em>inargN</em></span>).
</p>
<p>
Notice that no wrap nor limit mode is implemented. So, if an index attempt to access to a zone not allocated by the table, Csound will probably crash. However this drawback can be easily avoided by using wrap or limit opcodes applied to indexes before using <span class="emphasis"><em>vtablewi</em></span>, in order to correct eventual out-of-range values.
