Linux实用程序编写了一个matlab .mat文件

Consider the following text file file:

考虑以下文本文件:

1 2 3
4 5 6
7 8 9

I would like to have linux command writemat that does the following:

我想要linux命令writemat执行以下操作:

$ writemat --size=3,3 --outputFile=m.mat --name=A <file

producing a matlab .mat file m.mat, such that I can later do from within Matlab:

生成一个matlab .mat文件m.mat,这样我以后可以在Matlab中做:

>> s=load('m.mat')

s = 

    A: [3x3 double]

>> s.A

ans =

     1     2     3
     4     5     6
     7     8     9

Does such a command exist? Or do I have to write my own using the Matlab Application Programming interfaces? However, the latter feels somewhat like reinventing the wheel..

这样的命令存在吗?或者我是否必须使用Matlab应用程序编程接口编写自己的应用程序?然而,后者感觉有点像重新发明轮子..

This is not exactly what you want, but it may be equivalent: In Matlab you can load an ASCII file (like that in your example) using

这不是你想要的,但它可能是等价的:在Matlab中你可以加载一个ASCII文件(就像你的例子中那样)

load(name,'-ascii')

where name is a string containing the file name. The file contents are read into a Matlab variable with the same name as the file.

其中name是包含文件名的字符串。文件内容被读入与文件同名的Matlab变量。

If you need several variables in the same file, you could write the ASCII file as

如果在同一文件中需要多个变量,则可以将ASCII文件写为

a=[
1 2 3
4 5 6
7 8 9];
b=[
0 1 0 1];

(that is, add variable names and [, ], ; signs), and then run it from Matlab.

(即添加变量名称和[,],;符号),然后从Matlab运行它。
