Hi. so i am trying to solve this quetion: Write a function called flip_it that has one input argument, a row vector v, and one output argument, a row vector w that is of the same length as v. The vector w contains all the elements of v, but in the exact opposite order. For example, is v is equal to [1 2 3] then w must be equal to [3 2 1]. You are not allowed to use the built-in function flip.
my code for it is:
function w = flip_it(v)
v = [1 2 3 4 5];
w = v(end:-1:1);
For some reason I am getting an error. How do I fix it?

You're redefining v inside your function. So whatever you pass in gets ignored. Don't do that. Delete the line
v = [1 2 3 4 5];
and it should work fine.

You do not show a function named flip_it. What you show is some code that starts by calling a function named flip_it
