<p>All programs using FFTW should include its header file:
|
|
</p>
|
|
<div class="example">
|
|
<pre class="example">#include <fftw3.h>
|
|
</pre></div>
|
|
|
|
<p>You must also link to the FFTW library. On Unix, this
|
|
means adding <code>-lfftw3 -lm</code> at the <em>end</em> of the link command.
