matlab descending order algorithm without sort function

i want to know how to descending order (1Xn) matrix without sort function.

for example A=[1 3 6 9 8 5 10 2]

[Bjorn Gustavsson]

Why not use sort when someone paid to give you a software that has that function? Homework? If homework just look up any of the algorithms for sorting and implement (one of) them...

[Andrei Bobrov]

homework?

Please read here, point 4.

Answer 1

[Birdman]

A=[1 3 6 9 8 5 10 2];temp=0;
for i=1:j
    for j=1:length(A)
        if(A(i)>A(j))
            temp=A(i);
            A(i)=A(j);
            A(j)=temp;
        end
    end
end
disp(A)

This is bubble sorting algorithm.

hello,..

could you explain this code?? i have home work and this code works

[Bjorn Gustavsson]

Google bubble-sort. Look for bubble-sort videos on youtube. Look for bubble-sort on wikipedia. Run the script in debug-mode and look at how A changes step by step. We clearly understand this is a home-work. However, the idea with homework is that you should learn something from it. Read the link Andrei Bobrov gave. Check the link KSSV gave.

To run the scrip in debug-mode save the code snippet in a file, perhaps my_bubble_sort.m

then at the matlab command-line promp type:

>> dbstop in my_bubble_sort
>> my_bubble_sort

Then you run the sorting step-by-step and look at how your variable A changes betwee each step.

The common theme in each of the points here is: "you do"
