Member Function Documentation

double theplu::yat::regression::GSLInterpolation::evaluate ( double  x )

inherited

Calculate the interpolated value for x.

Returns

The interpolated value of for a given point x.

Exceptions

GSL_error

if evaluation is requested outside the range defined by the interpolation algorithm.

double theplu::yat::regression::GSLInterpolation::evaluate_derivative ( double  x )

inherited

Calculate the derivative of the interpolated function at x.

Returns

The derivative.

Exceptions

GSL_error

if evaluation is requested outside the range defined by the interpolation algorithm.

double theplu::yat::regression::GSLInterpolation::evaluate_derivative2 ( double  x )

inherited

Calculate the 2nd derivative of the interpolated function at x.

Returns

The 2nd derivative.

Exceptions

GSL_error

if evaluation is requested outside the range defined by the interpolation algorithm.

double theplu::yat::regression::GSLInterpolation::evaluate_integral ( double  a, double  b  )

inherited

Calculate the numerical integral of the interpolated function over the range .

Returns

The integral.

Exceptions

GSL_error

if evaluation is requested outside the range defined by the interpolation algorithm.

double theplu::yat::regression::GSLInterpolation::evaluation ( void  ) const

inherited

The result of the latest evaluaion function call is stored and can be retrieved with this function.

Returns

The latest evaluated value.

unsigned int theplu::yat::regression::GSLInterpolation::min_size ( void  ) const

inherited

This function returns the minimum number of points required by the interpolation type.

For example, Akima spline interpolation requires a minimum of 5 points.

Returns

The minimum number of points required.
