大規模な配列で作業しています。代わりに、サブアレイ上のinterp2
がそれを扱うことができない場合は、作業:
% Create data
format shortG
[Latitude,Longitude] = meshgrid(1:12,1:12);
Altitude = floor(1000+sortrows(rand(12,12))*1000);
Temperature = 10+20*rand(12,12);
Lat = 2.1;
Lon = 11.8;
% Find closest match point
[~,i_Lat] = min(abs(Latitude(1,:)-Lat));
[~,i_Lon] = min(abs(Longitude(:,1)-Lon));
% Select subarrays around this point.
% Minimum size of these matrices depend on the type of interpolation you perform
ia1 = max(1,i_Lat-5);
ia2 = min(size(Latitude,1),i_Lat+5);
io1 = max(1,i_Lon-5);
io2 = min(size(Latitude,2),i_Lon+5);
subLatitude = Latitude(io1:io2,ia1:ia2);
subLongitude = Longitude(io1:io2,ia1:ia2);
subAltitude = Altitude(io1:io2,ia1:ia2);
subTemperature = Temperature(io1:io2,ia1:ia2);
% Interpolate on these small arrays, and evaluate at target (Lat, Lon) point
A_out = interp2(subLatitude, subLongitude, subAltitude, Lat, Lon)
T_out = interp2(subLatitude, subLongitude, subTemperature, Lat, Lon)
あなたの行列の次元は何ですか? 'Latitude'と' Longitude'はすでにmeshgridですか? – m7913d
