word中怎么能将文章设置成段落式，即标题为“第几章”然后为1.1,1.2,1.3等等依次往下_百度知道matlab怎么在图上标出具体点坐标?图上的坐标怎么标出?原程序&&x=[0&1&2&3&4&5&6&7&8&9&10&11&12&13&14&15&16&17&18&19&20&21&22&23&24&25&26&27&28&29&30&31&32&33&34&35&36&37&38&39];y2=[0&3.75&10.95&19.95&29.3&38.45&46.85&54.50&61.55&68.00&73.85&78.95&83.75&88.25&92.3&95.9&99.2&102.2&104.9&107.3&109.55&111.65&113.6&115.4&117.05&118.55&119.9&121.1&122.15&123.05&123.8&124.4&124.85&125.25&125.61&125.91&126.11&126.26&126.36&126.44];plot(x,y2);hold&y3=126.44plot(x,y3,'-')

对巳知坐标的点,可以这样标出：plot(5,38.45,'rs','MarkerEdgeColor','k','MarkerFaceColor','g','MarkerSize',5)text(5,38.45,'(5,38.45)','EdgeColor','red','VerticalAlignment','bottom');plot(38,126.36,'rs','MarkerEdgeColor','k','MarkerFaceColor','g','MarkerSize',5)text(38,126.36,'(38,126.36)','EdgeColor','red','VerticalAlignment','bottom');对未知坐标的点,可以先插值,再标出：以下代码在7.1版以上均可运行.close allclear,clcx=[0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39];y2=[0 3.75 10.95 19.95 29.3 38.45 46.85 54.50 61.55 68.00 73.85 78.95 83.75 88.25 92.3 95.9 99.2 102.2 104.9 107.3 109.55 111.65 113.6 115.4 117.05 118.55 119.9 121.1 122.15 123.05 123.8 124.4 124.85 125.25 125.61 125.91 126.11 126.26 126.36 126.44];plot(x,y2);y3=126.44;plot(x,y3,'-');% Set up fittype and options.ft = 'linearinterp';opts = fitoptions( ft );opts.Normalize = 'on';% Fit model to data.fitresult = fit( x',y2',ft,opts );xx1 = [6.321,11.15,21.15]; % x = [6.321,11.15,21.15]yy1 = fitresult( xx1 ); % 与x对应的y值% 画点 标注for i = 1:length(xx1)plot(xx1(i),yy1(i),'rs','MarkerEdgeColor','k','MarkerFaceColor','g','MarkerSize',6)text(xx1(i),yy1(i),['(',num2str(xx1(i),'%5.2f'),',',num2str(yy1(i),'%5.2f'),')'],'EdgeColor','red','BackgroundColor',[.7 .9 .7],'VerticalAlignment','bottom');end
我要标出y值为49.31,79.66对应的坐标
程序怎么写？

以下代码在7.1版以上均可运行。
x=[0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39];

plot(x,y2);
y3=126.44;
plot(x,y3,'-');
% Set up fittype and options.
ft = 'linearinterp';
opts = fitoptions( ft );
opts.Normalize = 'on';
% Fit model to data.
fitresult = fit( y2', x', ft, opts );
yy1 = [49.31,79.66];
y = [49.31,79.66]
xx1 = fitresult( yy1 );
与y对应的x值
for i = 1:length(xx1)
plot(xx1(i),yy1(i),'rs','MarkerEdgeColor','k','MarkerFaceColor','g','MarkerSize',6)
text(xx1(i),yy1(i),['(',num2str(xx1(i),'%5.2f'),',',num2str(yy1(i),'%5.2f'),')'],'EdgeColor','red','BackgroundColor',[.7 .9 .7],'VerticalAlignment','bottom');
