<h1>插值器（[name]）</h1>

<p class="desc">
|
||
|
|
A参数样本上插值的抽象基类 <br /><br />
|
||
|
|
|
||
|
|
参数域是一维的，通常是数据定义的曲线上的时间或路径。<br /><br />
|
||
|
|
|
||
|
|
示例值可以具有任何维度，派生类可以对数据应用特殊的解释。<br /><br />
|
||
|
|
|
||
|
|
该类提供间隔查找的模板方法，将实际的插值延迟到派生类。<br /><br />
|
||
|
|
|
||
|
|
对于最多两个点之间的访问时间复杂度为O(1)，对于随机访问时间复杂度为O(log N)，其中N为位置数。<br /><br />
