Detailed Description

template<class T>
class statismo::Nystrom< T >

Computes the Nystrom approximation of a given kernel The type parameter T is the type of the dataset (e.g. Mesh, Image) for which the nystom approximation is computed

Member Function Documentation

template<class T>

MatrixType statismo::Nystrom< T >::computeEigenfunctionsAtPoint ( const PointType &  pt ) const

inline

Returns a d x n matrix, which holds the d-dimension value of all the n eigenfunctiosn at the given point

template<class T>

const VectorType& statismo::Nystrom< T >::getEigenvalues ( ) const

inline

Returns a vector of size n, where n is the number of eigenfunctions/eigenvalues that were approximated
