Having a function input be a function handle

Hi I am trying to make it so one of my inputs is a function handle so for example make it sin(x). Here is the code I have written so far. Thank you in advance for any help you can offer.

function []=Desmond(myfunction,n)
mytest=@(x) sin(x)
mytest=myfunction
x=-10:10;
y=myfunction(x).^n;
plot(x,y)
end

- if you want to pass a function handle into your code, then just prefix the function name with @. For example, if your code is

 function Desmond(hFunc,n)

     x=-10:10;
     y= hFunc(x).^n;
     plot(x,y)

 end

then to pass sin into this function you would simply call the above as

 Desmond(@sin,10)

Thank you so much for the help. I am still confused though as to where you set the value of sin x (ex sin(3). Also when I run your example I get this error. Conversion to double from function_handle is not possible.

Actually I figure out the problem. My other question is what if you want the function input to be ^2?

[Geoff Hayes]

If you want to define your own function handle, you could try

 func = @(x)x.^2;
 Desmond(func,10);
