<h2>Sampling Gabor Ridge</h2>


<h3>Description</h3>

<p>
Given a ridge phi (for the Gabor transform), returns a 
(regularly) subsampled version of length nbnodes.
</p>


<h3>Usage</h3>

<pre>
RidgeSampling(phi, nbnodes)
</pre>


<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>phi</code></td>
<td>
ridge (1D array).
</td></tr>
<tr valign="top"><td><code>nbnodes</code></td>
<td>
number of samples.
</td></tr>
</table>

<h3>Details</h3>

<p>
Gabor ridges are sampled uniformly.
</p>


<h3>Value</h3>

<p>
Returns a list containing the discrete values of the ridge.
</p>
<table summary="R argblock">
<tr valign="top"><td><code>node</code></td>
<td>
time coordinates of the ridge samples.
</td></tr>
<tr valign="top"><td><code>phinode</code></td>
