Matlab 的 EPS 输出好象是不太好。 试着调整一下 paperposition和 paperorientation。 比如, % x below is the figure number set(x, 'paperpositionmode', 'auto'); % auto means print the figure as its original size % according to the width/height ratio of the figure: set(x, 'paperorientation', 'landscape'); % or set(x, 'paperorientation', 'portrait'); % saveas(x, file_name_with_extension);
