No, but you could write a class and define FUN1 & FUN2 as its methods.

Ran in:
variablefun('fun2')
fun2 here
function variablefun(fun)
eval(fun)
function fun1
disp('fun1 here')
end
function fun2
disp('fun2 here')
end
end
However, you cannot use
writefun(fun2)
as fun2 will not be defined at that point. MATLAB always works by evaluating parameters first before calling the given function, so in MATLAB it is not possible at all to define special "unevaluated parameter" behaviour (such as Maple is able to do.)
