Geocode one grid from 2 grids with latitude and longitude values

Hi.

I have 3 matrices exactly with the same dimensions. One represents the variable of interest; one matrix has the longitude values; and the other the latitude values.

How can I geocode my matrice using the data from the two other matrices ?

Thanks Marco

variant: use TriScatteredInterp

doc TriScatteredInterp

eg:

V = randi([-100 200],8,4) % your variable of interest
lon = randi([-30 -50],8,4) % your longitude values (deg)
lat = randi([20 40],8,4) % your latitude  values (deg)

F = TriScatteredInterp(lon(:),lat(:),V(:)) % your interpolant
v = F(mean(lon),mean(lat)) % use function
