Detailed Description

template<typename T>
class InterpolationAtPoint< T >

Interpolates a partial solution linearly at a given point and adds this value multiplied by a given factor to the sparse grid solution.

This accumulator works with different types of grids: those having the dofs in the nodes, containing the boundary nodes or not, and those that with the dofs in the centers of the cells or on the cell edges/sides. The type of the grid is specified by the array of the shifts of the first/last grid points from the boundary: For every dimension there is the value specifying this shift in the units of the grid step. The possible values are in particular 0 for the node-centered grids with the boundary nodes, 0.5 for the cell-centered grids, 1 for the node-centered grids without the boundary nodes.

Note:

1. The point at which the value should be computed, may not lie in the shift area but only inside a grid cell or in a cell edge/side. Thus, for the shifts > 0 you may NOT specify a point on the boundary.
2. The point where should be specified by its coordinates in the unit hypercube.
