Answer 1

FID_IN=fopen('d:\data.txt');
C=textscan(FID_IN,'%05d');
fclose(FID_IN);
FID_OUT = fopen('d:\out.txt','w');
fprintf(FID_OUT,'%05d\r\n',C{1});
fclose(FID_OUT);
其中out.txt为输出结果

Answer 2

fp1 = fopen('data.txt','r');
fp2 = fopen('data2.txt','w');
while 1
str = fgetl(fp1);
if length(str) > 0 & str ~= -1
for ii = 1:floor(length(str)/5)
fprintf(fp2,'%s ',str((ii-1)*5+1 : ii*5));
end
fprintf(fp2,'\n\r');
else
break;
end
end
fclose(fp1);
fclose(fp2);
