Program: MKLSGRIDSTATTRILAYER
mklsgridstattrilayer.......statistical analysis of triangular layer
call: reslist=mklsgridstattrilayer(lsopt,layer);
reslist=mklsgridstattrilayer(lsopt,layer,mode);
lsopt: (struct)
LOCSMITH options structure as returned by MKLSOPT
layer: (struct)
layer structure as returned by MKGRIDNEWTRILAYER
mode: (string)
evaluation mode. The foloowing modes are available:
'length': edge lengths in km are determined
(only for triangles that have nodes as
children)
'circle': circlumcircle radii in degrees are determined
(only for triangles that have nodes as
children)
'circlekm': as 'circle', but with radii in km
'iterations': the number of iterations applied to
each triangle
DEFAULT: 'circle'
result: reslist: (numeric array)
vector containing lenghts or radii (depending on MODE)
of all edges/triangles. Lengths are in km or degrees
depending on MODE.
From this, histograms may be produced by hist(reslist);
performs statistical analyses of the point distribution in a layer:
- triangle area (spherical triangle, in km^2)
- point distance (great circle distance in km)
Analyzes only triangles with childtype=='node'. Triangles with childtype
'triangle' are ignored. Other childtypes cause errors.
Plots are produced if no output parameter is specified.
