我要讲一个txt文件中的一些中文字去掉，只剩下数据，由于数据量很大，手动不显示，故想通过matlab程序来实现，由于对matlab这方面的了解不够，所以来想各位大侠请教！谢谢！
现列举一部分的数据如下：
Separator Tab
Decimal_Separator .
Multi_Headings Yes
X_Columns No
Time_Pref Relative
Operator Administrator
Date 2010/04/26
Time 15:59:34.84375
***End_of_Header***
Channels 3

Time 15:59:34.84375 15:59:34.84375 15:59:34.84375

500.016527 0.577526 24.472467
我自己也找了一些相应的程序，但运行起来有问题，程序如下：
clc;
clear;
fidin=('test.txt');
fidout=fopen('A.txt','w');
while feof(fidin)==1;
tline=fgetl(fidin);
if double(tline(1))>=48&&double(tline(1))<=57
fprintf(fidout,'%s/n/n',tline);
contine
end
end
fclose(fidout);
MK=importdata('A.txt');
提示错误如下：
??? Error using ==> feof
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in ==> abc at 5
while ~feof(fidin)==1;
希望各位大侠不吝赐教~~ 谢谢！
