These are thress matrices with the same size, 2630x1083 double, it is actually remote sensing data in netcdf format. I want to get the values corresponding to the coordinates. thanks

I have a very simple question,
I have 3 matrices extracted from a netcdf file, latitude, longitude, and data values (Z). I would like to know the Z values corresponding to specific latitude and longitude points. How can I do this?
Thanks

You can do this a few ways. If you know the exact lat and lon you're interested in, say (30N,120E), it's simply
Z(lat==30 & lon==120)
Alternatively, you can use interp2.

Once you know the index to the lat/lon point you want, you can extract just the value there using ncread. In other words you don't have to pull the whole matrix into Matlab.
