Detailed Description

A natural cubic spline interpolation class.

Constructor & Destructor Documentation

spline() [1/2]

template<typename DataPoints = std::vector<vec2>>

theoretica::spline::spline ( const DataPoints &  p )

inline

Construct the natural cubic spline interpolation from a vector of coordinate pairs.

The x[i] values must be strictly increasing, an error is raised otherwise.

spline() [2/2]

template<typename Dataset1 , typename Dataset2 >

theoretica::spline::spline ( const Dataset1 &  X, const Dataset2 &  Y  )

inline

Construct the natural cubic spline interpolation from the sets of x[i] and y[i] data points.

The x[i] values must be strictly increasing, an error is raised otherwise.
