How to generate an m-file only with MATLAB codes?

I want to generate an m-file only with MATLAB codes. Can any experts help me with it?

For example, the whole process can contain two steps: 1) create an m-file called abc.m,

2) write three lines in the file a = 1; b = 2; c = a + b;

How can I do that? By the way, I got two operating systems for MATLAB R2013a (8.1.0.604): - PC, Windows 7 - Mac, OS X (10.9.3)

Thanks in advance!

[ES]

fName= 'abc.m';
fid = fopen(fName,'a'); %a for append, you can use 'w' instead to write freshly
fprintf(fid ,'%s\n','a = 1; b = 2; c = a + b;'); % '%s is for string
fclose(fid);
