You can do that, but you can only invoke them from inside the script, with one exception:
In order to invoke those functions from outside the script, the code of the script would have to take handles of the functions and save the handles in some known location. For example,
H{1} = @fun1;
H{2} = @fun2;
set(0, 'UserData', H);
function y = fun1(x)
y = x.^2 - 3;
end
function y = fun2(x)
y = sin(x) ./ exp(x);
end
Then in this example, you could call upon those functions from outside the script by using
H = get(0, 'UserData');
H{1}(3.81)
See also packages and static methods of classes.
If you were defining a function instead of a script, you would also have the option of using a "switchyard" design, such as:
function h = get_fun(funname)
switch funname
case 'f2m'
h = @f2m;
case 'm2f'
h = @m2f;
otherwise
h = @(varargin) error('unknown function name "%s"', funname);
end
end
function m = f2m(f)
m = f*whatever;
end
function f = f2m(m)
f = m/whatever;
end
