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 =)
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 =)
