如图所示,打开matlab软件界面 如图所示,点击勾选的新建脚本文件按钮 如图所示,输入以下代码 t=0:pi/50:2*pi; x=8*cos(t); y=4*sqrt(2)*sin(t); plot(x,y,'p');生成了一个如图所示的图形,但是坐标轴刻度字体有点小 如图所示,加入以下代码; set(gca,'FontSize',20,'Fontname', 在MATLAB 中,可以...
例如用imread读取一张图片,用im2bw转换成位图,方法如下:clear I=imread('abc.png');imshow(I);IY=im2bw(I,0.5);figure;imshow(IY)[m n]=size(IY) 改变窗口大小用set这个命令,一个简单的例子见下:t = 1: 10;y = 3*t;figure(1);plot(t,y,'x-r');hFig = figure(1);x = 10;y = 220;wid...
The second is to change the text label after plotting ThemeCopy loadcarsmall h = boxplot(MPG, Origin); set(findobj(get(h(1),'parent'),'type','text'),'fontsize', 30); It is not clear to me whatboxplotis actually returning. It is an array of handles, when I would have expect t...

Next comes the axes (system s in figure. The size) the and position of the axes system depends on the figure. For example, if you shrin K the size of the figure, the size of your plot will change accordingly. On the other hand, if you change the size of a subplot/axes, the ...

可以用 num2str() 函数转换数字到字符串 比如 》p = 2;text(x,y,num2str(p));%相当于text(x,y,'2')你做一循环，就可把它添加上去了 for ```text(x,y,num2str(p(i)));```你可以用legend函数啊，这是
