Program: MKLONLAT2XY
mklonlat2xy.......transform lon/lat coordinates to x/y coordinates acc. to MAPOPT
call: [x,y]=mklonlat2xy(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
MKLONLAT2XY dispatches the data to the respective projection routines.
Nothing is plotted here.
