Yes you can do this. Any M-file can call any other M-file as long as they are in the same directory or on the path. For example, put all of this into an M-file called myvars:
a_var = 5;
b_var = 7;
t = a_var + b_var;
f_func = @(x) x.^2;
Once this is done, then do this from the command line:
myvars
a_var + 10
f_fun(1:5)
You will see that whatever you define in myvars is available at the command line once the M-file is called. It is the same in another M-file. Just put the line:
myvars
anywhere in the file, then after that line all of the stuff in myvars will be in available in the calling file.
