For comparison of the query image histogram with the histograms of all images, how to store all the histograms in a feature vector folder?

在 MATLAB Online 中打开

fv_folder = 'feature_vectors';
for K = 1 : 10
  histogram = hist(.....);
    filename = sprintf('hist_%03d.mat', K);
    save( fullfile(fv_folder, filename), 'histogram')
  end
