Member Function Documentation

template<typename T >

T spams::FISTA::Ridge< T >::eval ( const Vector< T > &  x ) const

inlinevirtual

Implements spams::FISTA::Regularizer< T >.

Here is the call graph for this function:

template<typename T >

void spams::FISTA::Ridge< 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

Implements spams::FISTA::Regularizer< T >.
