[求助] 帮忙看一段程序

程序的目的是打开*.txt文件并把数据放入矩阵中，下面是编写的程序，其中 if row*col+2==rdata这个条件能成立吗，是什么意思？非常感谢！（*.txt文件的内容附在后面）。
%打开文件，读取数据
[Filename,Pathname]=uigetfile('*.txt','请打开数据文件');
fid=fopen([Pathname Filename],'r');
[data,count]=fscanf(fid,'%f,%f',inf);
fclose(fid);
%**********************判断数据是否正确*********************************
[rdata,ldata]=size(data);
row=data(1,1);
col=data(2,1);
if ~(rdata)==0
    if  row*col+2==rdata
        fprintf('\n\n^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^\n');
        fprintf('           @数据导入成功！@\n');
        fprintf('        矩阵的维数为%dx%d\n\n',row,col);
        fprintf('^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^\n\n');
    else
        fprintf('\n\nvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv\n');
        fprintf('           @数据文件格式错误！@\n');
        fprintf('vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv\n\n');
        break;
    end
else
    fprintf('\nvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv\n');
    fprintf('               @文件打开失败!@\n');
    fprintf('vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv\n\n');
    break;
end

我同意叔本华的观点，人们投身艺术和科学领域的强烈愿望之一就是逃离痛苦、残酷和枯燥无味的现实生活，逃离自己飘忽不定的七情六欲的桎梏。--爱因斯坦

从你的代码来看，文件数据非常简单，就是两列数值。这种情况下不要用 fopen  fprintf 之类的低级文件IO函数。直接用load即可，装入的矩阵自动为两列的，每列对应你的文件的每列数据

那我要调用好多个文件怎么用load函数呢？
