我的文件夹有三个txt文件我写了下面这个循环但是只能读取文件夹里的第一个文件，程序也没显示错误但是为什么不循环不能读取三个文件呢？该如何写？求大神指点。 dir_to_search = 'C:\Users\SJ\Desktop\zubair'; txtpattern = fullfile(dir_to_search, '*.txt'); dinfo = dir(txtpattern); for K = 1 : length(dinfo)   thisfilename = (dinfo(.name);  %just the name   thisdata = load(thisfilename); %load just this file    % [T(:,j),Spa(:,j),Spv(:,j),Sd(:,j)]=SPEC(dt,Ag,zet,g,endp); NS(:,K)=thisdata(:,2)/9.81; EW(:,K)=thisdata(:,3)/9.81;   %fprintf( 'File #%d, "%s", maximum value was: %g\n', K, thisfilename, max(thisdata() );   %do something with the data end

改成thisfilename = (dinfo(K).name);  %just the name
