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

Calculate the interpolated value for x.

Returns
The interpolated value of $ y $ for a given point x.
Exceptions
GSL_errorif 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_errorif 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_errorif 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 $ [a,b] $.

Returns
The integral.
Exceptions
GSL_errorif 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.
