<dd><p>Douglas-Peucker curve reduction algorithm.</p>
<p>This function receives a list of points as input and returns a simplified list by
eliminating redundancies.</p>
<p>A point is a tuple (or a list) of two floats, time and value. A list of points looks like:</p>
<blockquote>
<div><p>[ (0, 0), (0.1, 0.7), (0.2, 0.5), … ]</p>
</div></blockquote>
<dl class="field-list simple">
<dt class="field-odd">Args</dt>

<dt>pointlist: list of lists or list of tuples</dt><dd><p>List of points (time, value) to filter.</p>
</dd>
<dt>tolerance: float, optional</dt><dd><p>Normalized distance threshold under which a point is
excluded from the list. Defaults to 0.02.</p>
