# grid_igloo.m

Igloo grid, as per Appendix A2 of (http://dx.doi.org/10.1016/j.jmr.2014.05.009).

## Syntax

    [alps,bets,gams,whts,vorn]=grid_igloo(n_long)


## Arguments

    n_long - number of longitudes in the grid


## Outputs

     alps - alpha Euler angles of the grid (radians),
zeros because these are two-angle grids

bets - beta Euler angles of the grid (radians)

gams - gamma Euler angles of the grid (radians)

whts - Voronoi tessellation body angle weights

vorn - a cell array of matrices containing the
coordinates of the vertices of the Voro-
noi polyhedra


## Examples

Below is the Voronoi polyhedra diagram returned by grid_igloo(20).

## Notes

If no outputs are requested, a schematic is drawn.
