Example:

x = 0:.1:1;

y = [x; exp(x)];

fid = fopen('exp.txt', 'w');

fprintf(fid, '%6.2f %12.8f\n', y);

fclose(fid)

把这个代码执行一下，可能不会换行的，那再试一下下面的代码

x = 0:.1:1;

y = [x; exp(x)];

fid = fopen('exp.txt', 'wt');

fprintf(fid, '%6.2f %12.8f\n', y);

fclose(fid)

这次就没有问题了，我们要注意fopne的参数wt 而不是 w，这是matlab的在线帮助的东东fid = fopen(filename, permission_tmode) on Windows systems, opens the file in text mode instead of binary mode (the default). The permission_tmode argument consists of any of the specifiers shown in the Permission Specifiers table above, followedby the letter t, for example 'rt' or 'wt+. On UNIX® systems, text and binary mode are the same. (UNIX is a registered trademark of TheOpen Group in the United States and other countries).就是有两种读取模式binary or text. When choosing the binary model,No characters are given special treatment. 所以我们选择要注明text模式。

另外，对于dlmwrite可用：

dlmwrite(filename, net, '-append', 'delimiter', '\t', 'precision', 6, 'newline', 'pc');
