Detailed Description

template<class Function_>
class Gudhi::coxeter_triangulation::Linear_transformation< Function_ >

Transforms the zero-set of the function by a given linear transformation. The underlying function corresponds to f(M*x), where M is the transformation matrix.

Template Parameters

Function_

The function template parameter. Should be a model of the concept FunctionForImplicitManifold.

Constructor & Destructor Documentation

Linear_transformation()

template<class Function_ >

Gudhi::coxeter_triangulation::Linear_transformation< Function_ >::Linear_transformation ( const Function_ &  function, const Eigen::MatrixXd &  matrix  )

inline

Constructor of a linearly transformed function.

Parameters

[in]	function	The function to be linearly transformed.
[in]	matrix	The transformation matrix. Its dimension should be d*d, where d is the domain (ambient) dimension of 'function'.
