如何在Matlab中保存多维数组? [英] How to save multi-dimensional array in matlab?

问题描述

我有一个数组M=(1000000,12,2,2).

如何将其写入文件以供日后使用?

How do I write it to a file to work on later?

save('filename.txt','M','-ASCII')

似乎不起作用...

此致

推荐答案

1)就像@Shai的回答一样，您可以将其保存为mat文件

1) just like the answer from @Shai, you can save it to be mat file

2)如果要将其保存为txt文件，则可以通过以下方式进行操作:

2) if you want to save it to be txt file, you can do it in this way:

clear;clc;
M=[1000000,12,2,2];
dlmwrite('a.txt',M); % save M to file--a.txt
type a.txt; % print content in a.txt
M = dlmread('a.txt'); % load content of a.txt to M and then you will have 'M=[1000000,12,2,2]'

3)您还可以使用fopen，fprintf，fclose将矩阵保存到文件中.检查这篇文章:如何在MATLAB中的.txt文件中保存数据

3) you can also use fopen, fprintf, fclose to save a matrix to a file. check this post: How to save data in .txt file in MATLAB

4)对于您拥有的代码，我对其进行了测试.有用.我拥有的Matlab版本是R2011b.请再次检查您的代码.我用来测试的代码如下:

4) for the code you have, I tested it. It works. The Matlab version I have is R2011b. please check your code again. The code I used to test is as follows:

clear;clc;
M=[1000000,12,2,2];

save('b.txt','M','-ASCII');

clear;clc;
M = load('b.txt','-ASCII');
