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.

Member Function Documentation

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 331 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 337 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 310 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 290 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 300 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 346 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.
