将矩阵写入文件时包含表头 [英] Include table header when writing matrix to file

问题描述

我使用dlmwrite将矩阵从Matlab写入文件:

I write a matrix from Matlab to a file using dlmwrite:

A = [1,2,3; 
     4,5,6; 
     7,8,9];

dlmwrite('output.txt', A, 'delimiter','\t');

这给了我这个output.txt:

1         2         3
4         5         6
7         8         9

现在，我想添加标题以具有以下结果:

Now I would like to add a header to have the following result:

columnA   columnB   columnC
1         2         3
4         5         6
7         8         9

我该如何实现?

推荐答案

基于

Building upon A. Visser's answer, I found the following solution:

A = [1,2,3; 4,5,6; 7,8,9];
out = fopen('output.txt','w');
fprintf(out,['ColumnA', '\t', 'ColumnB', '\t', 'ColumnC', '\n']);
fclose(out);
dlmwrite('output.txt', A, 'delimiter','\t','-append');
