Hi Everybody,
I am trying to save images but the outputs images were overturned (up down and down up). Therefor I used flipud but it isn't work.
Thank you in advance

if true
cd C:\Calculated_NDVI_Arcgis
dinfo = dir('*_B3*.tif');
nfile = length(dinfo);
filenames = {dinfo.name};
for K = 1 : nfile
b3_file{K} = filenames{K};
band_pos{K} = strfind(b3_file{K}, '_B3');
b4_file{K} = b3_file{K}; b4_file{K}(band_pos{K} + 2) = '4';
b3_data{K} = double( imread(b3_file{K}) );
b4_data{K} = double( imread(b4_file{K}) );
finalndvi{K} = (b4_data{K} - b3_data{K}) ./ (b4_data{K} + b3_data{K});
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
R = georasterref('RasterSize',size(finalndvi{K}),'LatitudeLimits',[30.95115,31.76385],'LongitudeLimits',[46.58315,47.43285]);
R= flipud(R);
geotiffwrite(sprintf('%d.tif',K),finalndvi{K},R);
end

I did flipping to the finalndvi like:
finalndvi{K}=flipud(finalndvi{K});
Then I got final flipped images:)

Try this:
R = R(end:-1:1,:,:);

Ah, you cannot usefully flipud the handle of the image that is returned: you either need to change the axes YDIR property or else flipud the data that you send to be imaged.
