MATLAB: How can i save data from 1*5 cell array into excel file. I have 5 images in loop and i extract glcm features now i want to save each imgaes features but only the last image data is saved.

extract glcm features

%path D:\matlab\data\Training\glossy\*.jpg
path='D:\matlab\data\Training\test\';
list=dir([path, '*.jpg']);
for x=1:length(list)
  images{x}=imread([path, list(x).name]); 
  if length(size(images{x}))==3 %check if the image I is color
    I=rgb2gray(images{x});
  end;
  offsets0 = [0 1; -1 1; -1 0; -1 -1];
  glcm1 = graycomatrix(I,'offset',offsets0);
  stats{x} = graycoprops(glcm1,{'all'});
  writetable(struct2table(stats{x}), 'test_glcmfeatures.csv')
end

Best Answer

A snippet from your code:
    for x=1:length(list)
        ...
        writetable(struct2table(stats{x}), 'test_glcmfeatures.csv')
    end
You are overwriting test_glcmfeatures.csv on every iteration of the loop.
Instead, one solution would be to change the file name and create a new file on each iteration.
    for x=1:length(list)
        ...
        writetable(struct2table(stats{x}), sprintf('test_glcmfeatures_%d.csv', x))
    end
Alternatively, if you want to write everything to the same file, try using the ' range ' (link) property. [Addendum] Or, as @dpb pointed out, you could just collect all of the stats data within the look at write it all in one file after the loop (which would be simpler than using the 'range' property).
