在 MATLAB Online 中打开

You can write a for-loop and save all the images in a cell array

P = 'C:\Users\sy\Desktop\miasdbv1.21\MIASDBv1.21';
D = dir(fullfile(P,'*.pgm'));
C = cell(size(D));
for i = 1:numel(C)
    filename = fullfile(P, D(i).name);
    C{i} = imread(filename);
end

Add breakpoints: https://www.mathworks.com/help/matlab/matlab_prog/set-breakpoints.html in your code and see if each line run correctly. You can check if imread() ic correctly loading the pgm files.
