Program: MKLSGRIDREFTRI
mklsgridreftri.......determine max circumcircle radii at different iterations
call: [ccrlist,ratios]=mklsgridreftri(gridbase,maxiter,doplot);
gridbase: (string)
this string deterines which grid base is
used. This must be one of the possible
values of the .grid_base field of the
LOCSMITH options structure (see
MKLSDEFAULTS).
maxiter: (numeric)
maximum number of iterations applied to the
grid.
doplot: (string)
if present, this must be a string that is
accepted as plotmode by MKLSGRIDPLOT.
result: ccrlist: (numeric array) [degree]
List of the determined circumcircle radii.
ccrlist(i) is the maximum circumcircle radius in degrees
of the grid after i-1 iterations (the 0-th iteration is
the initial grid).
Length is measured as great circle arc length.
ratios: (numeric array) []
List of ratios of circumcircle radii:
ratios(i) is the ratio of the max circumcircle radius
after i iterations ot the max circumcircle radius after
i-1 iterations. This list is derived from CCRLIST.
This routine determines how the maximum circumcircle radius of triangles
in a grid of % specified type changes with iteration, for a specified number of
iterations. These factors are needed for the grid construction, when the
number of iterations necesssary to reach a certain spatial resolution has
to be estimated.
The grid is iterated step by step until the specified max number of
iterations is reached, and all circumcircles are evaluated at each
iteration.
If no output argument is given, the max circumcircle radii are
written to the screen
