不好意思，3楼的是失误，不小心把一个表情点进代码里面去了
我的想法是先从原始数据里面把数据分成四组，分别为x,y,z,w，然后在写进另一文件proceseed_date.txt中，但是不知道哪里出错了，二切我不知道怎么去除那 ...

clear clc format = '%s %d %d %f'; [x y z w] = textread('origin_date.txt', format); fid = fopen('proceseed_date.txt', 'at'); format1 = 'TEMP %-8d %-7d %-f\n'; for i = 1:20 fprintf(fid, format1, y(i), z(i), w(i)); end fclose(fid);

clear clc format = '%s %d %d %f'; [x y z w] = textread('origin_date.txt', format); xx = x; for i = 1:size(x) xx{i} = strrep(x{i},'*',''); end fid = fopen('proceseed_date.txt', 'at'); format1 = '%-9s %-8d %-7d %-f\n'; for i = 1:20 fprintf(fid, format1, xx{i}, y(i), z(i), w(i)); end fclose(fid);
