在 MATLAB Online 中打开

Use fileparts():

imds = imageDatastore('*.png')
fullFileNames = vertcat(imds.Files)
for k = 1 : length(fullFileNames)
	[folder, baseFileNameNoExt, ext] = fileparts(fullFileNames{k});
	baseFileNameWithExt = [ baseFileNameNoExt, ext];
	fprintf('Base file name #%d = %s\n', k, baseFileNameWithExt);
end
