matlab如何添加图像阴影

1. rectangle

rectangle('Position',[100,300,70,50],'Curvature',[0,0],'LineWidth',2,'LineStyle','--','EdgeColor','r')

% rectangle('Position',[x,y,宽,高],'Curvature',[x曲率,y曲率],'LineWidth',‘线宽,'LineStyle','线型','雹哪EdgeColor','线色')

2. patch

H_pa = patch([0.02,0.02,2,2],[0.01, 10,10,0.01],[.8 .8 .8])

% patch([Xleft, Xleft, Xright, Xright], [Ydown, Yup, Yup, Ydown],[阴影颜色])

set(H_pa,'源槐码EdgeColor',[.8 .8 .8],'EdgeAlpha',0.5,'FaceAlpha',0.5)

%set(H_pa,'EdgeColor',[边框颜色],'EdgeAlpha',边框透明度,'FaceAlpha',阴明此影透明度)

qujian=inputdlg({'输入a','输入b'})%如 1 3

F1=str2double(qujian{1})

F2=str2double(qujian{2})

x=linspace(-5,5)

y=normpdf(x,0,1)

x1=F1:0.01:F2

y1=normpdf(x1,0,1)

figure('color','w')

plot(x,y,'弊族k')

xlabel('标准正态分布函数租稿弊')

hold on

area(x1,y1)

hold off

按上面语敬御句试试
