grid_fibon.m

Fibonacci type spherical quadrature grids, as per Appendix A.5 of (http://dx.doi.org/10.1016/j.jmr.2014.05.009).

Syntax

    [alps,bets,gams,whts,vorn]=grid_fibon(type,parm)


Arguments

     type - 'fibonacci', 'zcw', or 'zcwn'

parm - point count parameter, the resulting
grid will have 2*n+1 points ('fib'),
fibonacci(n+2) points ('zcw'), or n
points (zcwn).


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 figure produced by grid_fibon('zcwn',300).

Notes

If no outputs are requested, a schematic is drawn.
