i want to know how to descending order (1Xn) matrix without sort function.
for example A=[1 3 6 9 8 5 10 2]

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...

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.

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"
