Detailed Description

template<>
class ecl::Polynomial< 0 >

Specialisation for the zero-th order polynomial.

Represents a zero'th order polynomial (scalar). It is necessary to handle this separately as the derivatives do not return lower degree polynomials.

Polynomial, Math::Polynomials.

Constructor & Destructor Documentation

ecl::Polynomial< 0 >::Polynomial ( ) [inline]

Default constructor.

This initialises the scalar coefficient for the zero'th polynomial to zero.

Definition at line 295 of file polynomial.hpp.

virtual ecl::Polynomial< 0 >::~Polynomial ( ) [inline, virtual]

Definition at line 296 of file polynomial.hpp.


Member Function Documentation

Handle to the coefficient array, use to initialise the polynomial.

This returns a handle to the coefficient array. Use this with the comma initialiser to conveniently set the polynomial.

 Polynomial<0> p;
 p.coefficients() = 1;
 cout << p << endl; // 1.00
Returns:
Coefficients& : reference to the co-efficient array.

Definition at line 360 of file polynomial.hpp.

const Coefficients& ecl::Polynomial< 0 >::coefficients ( ) const [inline]

Non-modifiable handle to the coefficient array.

Returns:
const Coefficients& : non-modifiable reference to the co-efficient array.

Definition at line 366 of file polynomial.hpp.

double ecl::Polynomial< 0 >::dderivative ( const double &  ) const [inline]

Access the second derivative directly (always returns 0)..

Access the values of the second derivative directly (always returns 0)..

Returns:
double : 2nd derivative of a scalar is always 0.0.

Definition at line 339 of file polynomial.hpp.

Polynomial<0> ecl::Polynomial< 0 >::derivative ( ) const [inline]

Derivative of a zero'th order polynomial is always zero.

Derivative of a zero'th order polynomial is always zero.

Returns:
Polynomial<0> : the zero polynomial.

Definition at line 319 of file polynomial.hpp.

double ecl::Polynomial< 0 >::derivative ( const double &  ) const [inline]

Access the derivative directly (always returns 0).

Access the values of the derivative directly (always returns 0)..

Returns:
double : derivative of a scalar is always 0.0.

Definition at line 329 of file polynomial.hpp.

double ecl::Polynomial< 0 >::operator() ( const double &  ) const [inline]

Access the value of the polynomial at the specified point.

Access the value of the polynomial at the specified point.

Returns:
double : the value of a scalar is always a_0.

Definition at line 375 of file polynomial.hpp.

void ecl::Polynomial< 0 >::shift_horizontal ( const double &  ) [inline]

Horizontal shift transform.

Normally, shifts the polynomial along the x axis by the specified offset, but in the case of this specialisation, does not change the polynomial.
