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

CacheTaylorImplementation() [1/2]

template<typename T>

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

inline

Constructor with supplied value x.

Sets the first coefficient to x

References coeff_.

CacheTaylorImplementation() [2/2]

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 coeff_.

Member Function Documentation

resize()

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 coeff_, and resizeCoeffs().
