[求助] 大神们，求解释下面的这段小代码

filename='VV.TXT';
fid=fopen(filename,'r');
for i=1:924;
    for j=1:1001;
        vv(j)=fscanf(fid,'%f',1);
    end
end
for j=1:1001;
    vv(j)=fscanf(fid,'%f',1);
end
x=0:.0003:.3;
plot(x,vv);
title('Potential');
xlabel('x(cm)');
ylabel('U(V)');
fc=fclose(fid);

啥也没干，就把最后1000个数读到vv里面绘图。前面都是白读，为了读后面的。
