Detailed Description

template<typename T>
class Sacado::Tay::CacheTaylorImplementation< T >

Taylor polynomial class using caching expression templates.

This class provides the implementation of the Taylor object required for expression templating. Class CacheTaylor provides the complete user inteface.

Constructor & Destructor Documentation

template<typename T >

Sacado::Tay::CacheTaylorImplementation< T >::CacheTaylorImplementation ( const T &  x )

inline

Constructor with supplied value x.

Sets the first coefficient to x

template<typename T >

Sacado::Tay::CacheTaylorImplementation< T >::CacheTaylorImplementation ( int  d, const T &  x  )

inline

Constructor with degree d and value x.

Initializes first coeffienct to x and of a polynomial of degree d

References Sacado::Tay::CacheTaylorImplementation< T >::coeff_.

Member Function Documentation

template<typename T >

void Sacado::Tay::CacheTaylorImplementation< T >::resize ( int  d, bool  keep_coeffs  )

inline

Resize polynomial to degree d.

Coefficients are preserved if keep_coeffs is true, otherwise all coefficients are reset to zero.

References Sacado::Tay::CacheTaylorImplementation< T >::coeff_, and Sacado::Tay::CacheTaylorImplementation< T >::resizeCoeffs().
