Build a 2D spline approximation of a function.

Use the values of a function at known grid points (as specified by SplineBuilder2D::interpolation_domain_type) and the derivatives of the function at the boundaries (if necessary for the chosen boundary conditions) to calculate a 2D spline approximation of a function.

The spline approximation is stored as a ChunkSpan of coefficients associated with basis-splines.

Parameters

[out]	spline	The coefficients of the spline calculated by the function.
[in]	vals	The values of the function at the grid points.
[in]	derivs_min1	The values of the derivatives at the lower boundary in the first dimension.
[in]	derivs_max1	The values of the derivatives at the upper boundary in the first dimension.
[in]	derivs_min2	The values of the derivatives at the lower boundary in the second dimension.
[in]	derivs_max2	The values of the derivatives at the upper boundary in the second dimension.
[in]	mixed_derivs_min1_min2	The values of the the cross-derivatives at the lower boundary in the first dimension and the lower boundary in the second dimension.
[in]	mixed_derivs_max1_min2	The values of the the cross-derivatives at the upper boundary in the first dimension and the lower boundary in the second dimension.
[in]	mixed_derivs_min1_max2	The values of the the cross-derivatives at the lower boundary in the first dimension and the upper boundary in the second dimension.
[in]	mixed_derivs_max1_max2	The values of the the cross-derivatives at the upper boundary in the first dimension and the upper boundary in the second dimension.
