Detailed Description

This is a TabulatedFunction that computes a continuous two dimensional function.

Constructor & Destructor Documentation

Continuous2DFunction	(	int	xsize,
		int	ysize,
		const std::vector< double > &	values,
		double	xmin,
		double	xmax,
		double	ymin,
		double	ymax
	)

Create a Continuous2DFunction f(x,y) based on a set of tabulated values.

Parameters

values	the tabulated values of the function f(x,y) at xsize uniformly spaced values of x between xmin and xmax, and ysize values of y between ymin and ymax. A natural cubic spline is used to interpolate between the tabulated values. The function is assumed to be zero when x or y is outside its specified range. The values should be ordered so that values[i+xsize*j] = f(x_i,y_j), where x_i is the i'th uniformly spaced value of x. This must be of length xsize*ysize.
xsize	the number of table elements along the x direction
ysize	the number of table elements along the y direction
xmin	the value of x corresponding to the first element of values
xmax	the value of x corresponding to the last element of values
ymin	the value of y corresponding to the first element of values
ymax	the value of y corresponding to the last element of values
