Detailed Description

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.

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

Default constructor.

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

Member Function Documentation

◆ coefficients() [1/2]

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

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 366 of file polynomial.hpp.

◆ coefficients() [2/2]

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 372 of file polynomial.hpp.

◆ dderivative()

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 345 of file polynomial.hpp.

◆ derivative() [1/2]

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 325 of file polynomial.hpp.

◆ derivative() [2/2]

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 335 of file polynomial.hpp.

◆ operator()()

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 381 of file polynomial.hpp.

◆ shift_horizontal()

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.
