MATLAB如何加入滑动条，并能让滑动条滑动且得到相应数值？（要求代码，画滑动条，得数值)

想要两条就行，①往已知图片加slide,图片由imread导入，滑动条范围0~1，调节每次0.01.②在命令窗口获得由滑动条滑动所得数据，将数值赋予K。

Answer 1

h=figure('unit','normalized','name','Slider');
hsl=uicontrol('parent',h,'unit','normalized','style','slider','position',[.01.53 . 3 .04],'min',0,'max',5);
ht1=uicontrol('parent',h,'unit','normalized','style','text','string','0 5','position',[.01 .57 .3.04],'fontsize',10);
ht2=uicontrol('parent',h,'unit','normalized','style','text','position',[.01.71 .3 .03]);
set(hsl,'callback',['a1=get(hsl,''value'');'...
'set(ht2,''string'',a1);']);

连代码都无法运行。。。。想要两条就行，①往已知图片加slide,图片由imread导入，滑动条范围0~1，调节每次0.01.②在命令窗口获得由滑动条滑动所得数据，将数值赋予K。麻烦再写一下，会适当提高奖励的

回来晚了，，，根据图片大小不同，你自己调节position参数值，使它看着好看些，，K值也已经传到命令窗口了
h=figure('unit','normalized','name','Slider');
axes('parent',h,'unit','normalized');
Picture=imread('abc.jpg');%图片
imshow(Picture);
hsl=uicontrol('parent',h,'unit','normalized','style','slider','position',[.01 .53 .3 .04],'min',0,'max',1);
ht1=uicontrol('parent',h,'unit','normalized','style','text','string','0 5','position',[.01 .57 .3 .04],'fontsize',10);
ht2=uicontrol('parent',h,'unit','normalized','style','text','position',[.01 .71 .3 .03]);
set(hsl,'callback',['K=get(hsl,''value'');'...
'set(ht2,''string'',K);']);

Answer 2

gui 里面可以实现

能给出详细代码吗？画滑动条，得数值，两行就行
