Gridding Routines

FAST_GRID2 (points, grid_x)

Returns a gridded, 1D array containing Y values, given random X,Y coordinates (this function works best with dense data points).

FAST_GRID3 (points, grid_x, grid_y)

Returns a gridded, 2D array containing Z values, given random X, Y, Z coordinates (this function works best with dense data points).

FAST_GRID4 (points, grid_x, grid_y, grid_z)

Returns a gridded, 3D array containing intensity values, given random 4D coordinates (this function works best with dense data points).

GRID_2D (points, grid_x)

Returns a gridded, 1D array containing Y values, given random X,Y coordinates (this function works best with sparse data points).

GRID_3D (points, grid_x, grid_y)

Returns a gridded, 2D array containing Z values, given random X, Y, Z coordinates (this function works best with sparse data points).

GRID_4D (points, grid_x, grid_y, grid_z)

Returns a gridded, 3D array containing intensity values, given random 4D coordinates (this function works best with sparse data points).

GRIDN(d, i)

Grids n dimensional data.

GRID_SPHERE (points, grid_x, grid_y)

Returns a gridded, 2D array containing radii, given random longitude, latitude, and radius values.

INTERPOLATE(d, x)

Interpolates scattered data at scattered locations.
