<H2>NUM2HEX Convert Numbers to IEEE Hex Strings
</H2>
<P>
Section: <A HREF=sec_elementary.html> Elementary Functions </A>
<H3>Usage</H3>
Converts single and double precision arrays to IEEE hex strings. The
syntax for its use is
<PRE>
y = num2hex(x)
</PRE>
<P>
where <code>x</code> is either a <code>float</code> or <code>double</code> array. The output <code>y</code> is
a <code>n-by-p</code> character array, where <code>n</code> is the number of elements in <code>x</code>,
and <code>p</code> is 16 for <code>double</code> arrays, and 8 for <code>single</code> arrays.
<H3>Example</H3>
Some interesting numbers
<PRE>
--> num2hex([1 0 0.1 -pi inf nan])
ans =
3ff0000000000000
0000000000000000

7ff0000000000000
fff8000000000000
</PRE>
<P>
The same in single precision
<PRE>
--> num2hex(float([1 0 0.1 -pi inf nan]))
ans =
3f800000
00000000
