方式：

g = colormap(lines);hold on;
for i = 1:3
    x = 0:power(10,-i):2*pi;
    y = (exp(-x)) .* (sin((x.^2)/2));
    m = diff(y)./diff(x);
    plot(x(1:end-1),m,'Color',g(i,:));
end
hold off;
set(gca,'YLim',[-0.25,0.25]);
set(gca,'XLim',[0, 2*pi]);
set(gca,'XTick',0:pi/2:2*pi);
set(gca,'YTick',-0.2:0.1:0.2);
set(gca,'XTickLabel',{'0','\pi/2','\pi','3\pi/2','2\pi'});
h = legend('h=0.1','h=0.01','h=0.001');
box on;

编程两大法宝：

百度 + 再读一遍你写的代码
