<p>
The <CODE>IEQUAL</CODE> function returns the index of
<code>vector</code> which corresponds to where <code>vector</code> is equal to
the value of <code>scalar</code>, that is, <CODE>IEQUAL</CODE>
returns the first <code>j</code> where <code>vector[j] = scalar</code>. If the value
of <code>scalar</code> is not in <code>vector</code> then
<CODE>IEQUAL</CODE> returns zero (0).</p>
<P>
<font size="+1" color="green">Example</font></P>
<P>
Suppose you have vector <code>X = [1;2;3;4;5]</code>. If you enter
<CODE><font color="blue">A=IEQUAL(X,2)</font></CODE>, the scalar <code>A</code>
will have the value 2.</P>
