% Generate a grid on a sphere
There can be more than one sphere
The grid is evenly spaced in right ascension and elevation. You can
select either a spherical grid (with one point at the pole) or a
even distributed grid.
Type GenerateGrid for demo.
--------------------------------------------------------------------------
Form:
GenerateGrid;
[rA, dec, a, kDec, kR, r, nPL] = GenerateGrid( n, r, stayout, type )
--------------------------------------------------------------------------
------
Inputs
------
n (1,1) Number of increments of declination
r (1,:) Radius of sphere(s)
stayout (:) Stayout zones
.rOffset (3,1) Origin
.u (3,1) Centerline
.angle (1,1) Cone angle
type (1,:) 'globe' or 'spherical'
-------
Outputs
-------
rA (1,:) Right ascension
dec (1,:) Declination
a (1,:) 1 if active 0 if inactive
kDec (1,n) The first element in rA and dec for each
new declination.
kR (1,:) The first element of each new radius
r (1,:) Radii of grid points
nPL (1,:) Nodes per level
