Linux utility program to write a matlab .mat file

Consider the following text file file:

1 2 3
4 5 6
7 8 9

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

$ 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:

>> 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..

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

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.

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

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.
