Section: <A HREF=sec_transforms.html> Transforms/Decompositions </A>
<H3>Usage</H3>
The <code>hilbert</code> function computes the hilbert transform of the argument
vector or matrix. The FreeMat <code>hilbert</code> function is compatible with
the one from the MATLAB API. This means that the output of the
<code>hilbert</code> function is the sum of the original function and an
imaginary signal containing the Hilbert transform of it. There are
two syntaxes for the hilbert function. The first is
<PRE>
y = hilbert(x)
</PRE>
<P>
where <code>x</code> is real vector or matrix. If <code>x</code> is a matrix, then he
Hilbert transform is computed along the columns of <code>x</code>. The
second syntax provides a dimension along which to take the
transform.
<PRE>
y = hilbert(x,n)
</PRE>
<P>
where <code>n</code> is the dimension along which to apply the transformation.
