{{DISPLAYTITLE:grid_trian.m}} __NOTOC__
Triangular spherical quadrature grids, as per Appendix A.6 of (http://dx.doi.org/10.1016/j.jmr.2014.05.009).

==Syntax==

     [alps,bets,gams,whts,vorn]=grid_trian(type,n)

==Parameters==

      type - 'asg', 'sophe', or 'stoll'
 
         n - point count parameter

==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_trian('stoll',10).

==Notes==
If no outputs are requested, a schematic is drawn.
