在Matlab中将标题添加到矩阵 [英] Adding a header to a matrix in Matlab

问题描述

我希望你们到目前为止过的愉快.我意识到您不能在MATLAB中将字符串标题添加到数值矩阵中.我正在尝试将标头添加到当前具有的矩阵中，并将其输出到制表符分隔的文本文件中.根据我的研究，我知道必须将矩阵转换为单元格，但是使用dlmwrite保存单元格时遇到了麻烦.

I hope you guys are having a nice Tuesday so far. I realize that you cannot add a string header to a numerical matrix in MATLAB. I am trying to add headers to a matrix I currently have and output it to a tab-delimited text file. From my research, I know that the matrix has to be converted into a cell, but I am having trouble saving the cell using dlmwrite.

这是我当前拥有的矩阵:

Here is the matrix I currently have:

  0         0         0
0.0454    0.0105    0.0105
0.0907    0.0066    0.0068
0.1814    0.0038    0.0049
0.3629    0.0034    0.0040
0.7258    0.0029    0.0023
1.4515    0.0002    0.0007
2.9030    0.0003    0.0005

这就是我想要的:

 tau     TOL Adev  FOL Adev
0.0454    0.0105    0.0105
0.0907    0.0066    0.0068
0.1814    0.0038    0.0049
0.3629    0.0034    0.0040
0.7258    0.0029    0.0023
1.4515    0.0002    0.0007
2.9030    0.0003    0.0005

矩阵(第一行中的3，7为零)称为saveData.

The matrix(3, 7 with zeros in the first row) is called saveData.

我尝试分配标头= ['tau'，'TOL Adev'，'FOL Adev'];并输出= {header; saveData};但是我不知道如何使用dlmwrite('filename'，output，'\ t').

I have tried assigning header = ['tau', 'TOL Adev', 'FOL Adev']; and output = {header;saveData}; but I cannot figure out how to use dlmwrite('filename', output, '\t').

非常感谢您的帮助！ -亚历克斯

推荐答案

如果您感到懒惰并且矩阵不太大，则可以将数据制作为数据集，然后将其导出.如果矩阵很大，建议您查看Amro给出的链接.注释数据集是统计工具箱中的功能.

If you are feeling lazy and your matrix is not too big, you can make your data into a dataset, then export it. If your matrix is large, I recommend you look at the link Amro has given. Note dataset is a function in the Statistics Toolbox.

ds = dataset({rand(10,3) 'a' 'b' 'c'})
export(ds, 'file', 'foo.txt', 'delim', '\t');
