I need to create a user defined function that recieves a vector x of any length and than sorts the vector from the largest to the smallest into a new vector y. I'm not allowed to use the function sort. I have no idea how to begin! please help me!! thank u!!!

This article should be of help to you.

I tend to prefer the merge sort algorithm.

The most intuitive (and simple to implement) is probably bubble sort:
Since this is an assignment, I'll leave some of it open, so fill in the blanks =)
n=length(A);
for j=1:1:n-1
% comparing each number with the next and swapping
for i=1:1:n-1
if ...
% In here you should check if A(i) > A(i+1)
% If so, switch places. You need a temporary
% variable, in order to not overwrite something.
end
end
end
Good luck =)
