<h2>Reconstruction from Dual Wavelets</h2>
<h3>Description</h3>
<p>
Computes the the reconstructed signal from the ridge when the epsilon
parameter is set to zero, in the case of real constraints.
</p>
<h3>Usage</h3>
<pre>
zeroskeleton2(cwtinput, Qinv, morvelets, bridge, aridge, N)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>cwtinput</code></td>
<td>
continuous wavelet transform (output of <code><a href="cwt.html">cwt</a></code>).
</td></tr>
<tr valign="top"><td><code>Qinv</code></td>
<td>
inverse of the reconstruction kernel (2D array).
</td></tr>
<tr valign="top"><td><code>morvelets</code></td>
<td>
array of Morlet wavelets located at the ridge samples.
</td></tr>
<tr valign="top"><td><code>bridge</code></td>
<td>
time coordinates of the ridge samples.
</td></tr>
<tr valign="top"><td><code>aridge</code></td>
<td>
scale coordinates of the ridge samples.
</td></tr>
<tr valign="top"><td><code>N</code></td>
<td>
size of reconstructed signal.
</td></tr>
</table>
<h3>Details</h3>
<p>
The details of this reconstruction are the same as for the function
skeleton. They can be found in the text
</p>
<h3>Value</h3>
<p>
Returns a list of the elements of the reconstruction of a signal from
sample points of a ridge
</p>
<table summary="R argblock">
<tr valign="top"><td><code>sol</code></td>
<td>
reconstruction from a ridge.</td></tr>
<tr valign="top"><td><code>A</code></td>
<td>
matrix of the inner products.</td></tr>
<tr valign="top"><td><code>lam</code></td>
<td>
coefficients of dual wavelets in reconstructed signal. They
are the Lagrange multipliers <i>lambda</i>'s of the text.</td></tr>
<tr valign="top"><td><code>dualwave</code></td>
<td>
array containing the dual wavelets.</td></tr>
