問題在用Matlab控制谷歌代碼

Question

要使用MATLAB鏈接的java我用一個開源的，Matlab的控制谷歌代碼 我收到此錯誤：Error: At least one END is missing: the statement may begin here.
運行在命令行中的javac Dwtembed.java此代碼。
如果你複製粘貼下面的代碼並檢查，你會明白我實際上正在做什麼，這一點很清楚。我真的希望能爲這個問題找到一些幫助。

import matlabcontrol.*; 
class Dwtembed 
{ 
    public static void main(String[] args) throws MatlabConnectionException,   MatlabInvocationException 
    { 
     //Create a proxy, which we will use to control MATLAB 
     MatlabProxyFactory factory = new MatlabProxyFactory(); 
     MatlabProxy proxy = factory.getProxy(); 

     proxy.eval("file_name='lena.bmp';"); 
     proxy.eval("cover_object=double(imread(file_name));"); 
     proxy.eval("mc=size(cover_object,1);"); 
     proxy.eval("nc=size(cover_object,2);"); 
     proxy.eval("file_name='dmg2.bmp';"); 
     proxy.eval("message=double(imread(file_name));"); 
     proxy.eval("mm=size(message,1);"); 
     proxy.eval("nm=size(message,2);"); 
     proxy.eval("[ca,ch,cv,cd]=dwt2(cover_object,'haar');"); 
     proxy.eval("ca1=ca;"); 

     proxy.eval("qiangdu=1;"); 

     proxy.eval("for i=1:nm"); 
      proxy.eval("for j=1:nm"); 
       proxy.eval("if(message(i,j)==0)"); 
        proxy.eval("ca1(i,j)=ca(i,j)+qiangdu;"); 
       proxy.eval("end"); 
      proxy.eval("end"); 
     proxy.eval("end"); 

     proxy.eval("watermarked_image=idwt2(ca1,ch,cv,cd,'haar');"); 
     proxy.eval("watermarked_image_round=round(watermarked_image);"); 
     proxy.eval("watermarked_image_uint8=uint8(watermarked_image_round);"); 
     proxy.eval("imshow(watermarked_image_uint8);"); 

     proxy.eval("figure(2);"); 
     proxy.eval("imshow(watermarked_image_uint8,[]);"); 
     proxy.eval("title('watermarked image');"); 
     proxy.eval("imwrite(watermarked_image_uint8,'dwt_watermarked.bmp','bmp');"); 
     proxy.eval("xsz=mc*nc*max(max(cover_object.^2))./sum(sum((cover_object-watermarked_image_round).^2));"); 
     proxy.eval("psnr=10*log10(xsz);"); 



    //Disconnect the proxy from MATLAB 
    proxy.disconnect(); 
    } 
}

你不能eval的for S和if就像是，作爲for i=1:nm是不是本身就是一個有效的MATLAB語句。您需要完成的MATLAB語句的東西eval。

請嘗試將for或if聲明的全部內容放在一個單獨的eval中。
