Here is the call graph for this function:

template<typename T >

void spams::FISTA::TreeLasso< T >::fenchel ( const Vector< T > &  input, T &  val, T &  scal  ) const

inlinevirtual

returns phi^star( input ) and ouput=input if the fenchel is unconstrained returns 0 and scale input such that phi^star(output)=0 otherwise
