OK, one possibility (still rather imperfect) is to replace the
above with something like this:
classdef foo
methods (Static)
function f = run(a, b, c)
% the function formerly known as foo;
% it calls one or more of foo.bar, ..., foo.zzz
...
end
function b = bar(d, e)
...
end
...
function z = zzz(x, y)
...
end
end
end
Now all the functions are accessible from other files, and yet they
do not pollute the global namespace.
The one drawback I see is that, instead of calling foo(a, b, c),
one must call foo.run(a, b, c).
Are there other drawbacks I'm not seeing?
