what is wrong with my code

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.

hi, I do have the function called flip_it. so I am not sure what is wrong

[Walter Roberson]

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