Program: MKSTEREOGRAPHIC
mkstereographic........stereographic (azimuthal conformal)
call: [x,y]=mkstereographic(lon,lat,mapopt,direction);
lon: arbitrary matrix of longitude values [deg]
lat: arbitrary matrix of latitude values [deg]
mapopt: map options structure as returned by MKMAPOPT
direction: projection direction:
'forward': transform lon/lat to x/y
'inverse': transform x/y to lon/lat
result: x: matrix x coordinates
y: matrix of y coordinates
X and Y have same size and shape as LON and LAT (values with equal index correspond)
but are projected and scaled according to the settings in MAPOPT
The stereographich projection is a conformal azimuthal projection.
Circles on the globe are mapped to circles in the map.
