How to use interpolation?
显示 更早的评论
I have longitude, latitude, the veolocity of sea surface and a buoy velocity
I want to know the relationship between sea surface velocity and buoy velocity
so i want to interpolate the velocity of sea surface using interp2
in this case how do i make the function?

Let lon,lat,U be your 2D data, and x,y,u be your buoy data.
Ui = interp2(lon,lat,U,x,y) ;
If your data is #d (I hope it is), then run loop for each time step.
Other option is; get the index of nearest neightbour of (x,y) in (lon,lat) and extract U for this index.
