刚刚搜索了以下这个发面的帖子，找到了办法，但是运行报错，如下：
fidin=fopen('D:\shuju.txt'); % 打开txt文件
fidout=fopen('D:\newsj.txt','w'); % 创建txt文件
while ~feof(fidin) % 判断是否为文件末尾
tline=fgetl(fidin); % 从文件读行
if double(tline(1))>=48&&double(tline(1))<=57 % 判断首字符是否是数值
fprintf(fidout,'%s\n\n',tline); % 如果是数字行，把此行数据写入文件MKMATLAB.txt
continue % 如果是非数字继续下一次循环
end
end
fclose(fidout);
MK=importdata('D:\newsj.txt'); % 将生成的.txt文件导入工作空间，变量名为MK，实际上它不显示出来

运行报错：
??? Error using ==> feof
Invalid fid.

我已经将frogfish 大 贴中的文件名改成我的文件名了啊...

估计句柄 fidin 有误，建议自己设置断点调试一下便可
