Function Documentation

RealVec exafmm_t::surface(int p, real_t r0, int level, real_t *c, real_t alpha)

Given a box, calculate the coordinates of surface points.

Parameters

• p – Order of expansion.

• r0 – Half side length of the bounding box (root node).

• level – Level of the box.

• c – Coordinates of the center of the box.

• alpha – Ratio between the side length of surface box and original box. Use 2.95 for upward check and downward equivalent surface, use 1.05 for upward equivalent and downward check surface.

Returns

Vector of coordinates of surface points.
