<h3>template<class TPointContainer, class TWeightContainer><br>
class itk::BarycentricCombination< TPointContainer, TWeightContainer ></h3>
Class that computes the barycentric combination of an array of N points<p>
An array of (N-1) values is expected to weight the contribution of the first (N-1) points, the weight of the Nth point is computed to ensure that the N weights sum 1.<p>
This method computes:<p>
<p class="formulaDsp">
<img class="formulaDsp" alt="\[ \overrightarrow{P}= \sum_{i=1}^{N-1} w_i * \overrightarrow{P}_i + \left(1- \sum_{i=1}^{N-1} w_i\right) * \overrightarrow{P}_N \]" src="form_165.png">
<p>
<p>
The points are expected to be stored in an itkContainer class like <a class="el" href="classitk_1_1VectorContainer.html">itk::VectorContainer</a>, responding to the Begin(), End(), Value() API.<p>
The weights are expected to be stored in any array-like container having a operator[i].
