建立如下函數(shù)

    function printscreen(picname)
        robo = java.awt.Robot;
        t = java.awt.Toolkit.getDefaultToolkit();
        rectangle = java.awt.Rectangle(t.getScreenSize());   
        name1=strcat(picname,'.png');
        image = robo.createScreenCapture(rectangle);
        filehandle = java.io.File(name1);
        javax.imageio.ImageIO.write(image,'png',filehandle);
    end

輸入?yún)?shù)為要保存的文件名稱(chēng)
如

printscreen('屏幕截圖')

如果后面要把MATLAB編譯為Exe的話，需要引入對(duì)應(yīng)的java包，如下

 function printscreen(picname)

import java.awt.Rectangle; 
import java.awt.Robot; 
import java.awt.Toolkit; 
import java.io.File; 
import javax.imageio.ImageIO; 

        robo = java.awt.Robot;
        t = java.awt.Toolkit.getDefaultToolkit();
        rectangle = java.awt.Rectangle(t.getScreenSize());   
        name1=strcat(picname,'.png');
        image = robo.createScreenCapture(rectangle);
        filehandle = java.io.File(name1);
        javax.imageio.ImageIO.write(image,'png',filehandle);
    end
