在 MATLAB Online 中打开

colortable = [0 0 0;      %black
              0 .8 .1;    %bright-ish green-ish
              .05 .5 0.05;     %darker green-ish
              ...         %etc
             ];
for K = 1 : number_of_segments
   these_x = segment_x{K};
   these_y = segment_y{K};
   this_color = colortable(K,:);
   plot(these_x, these_y, 'Color', this_color);
   hold on
end
