function name as a variable

Is it possible to do the following?

variablefun.m

function variablefun(fun)
fun
    function fun1
    end
    function fun2
    end
end

command window

variablefun(fun1)
variablefun(fun2)

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

also a good idea thanks

Answer 1

[Walter Roberson]

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.)

thank you so much that works
