Remove all the redundant elements in a vector, but keep the first occurrence of each value in its original location. So if
a = [5 3 6 4 7 7 3 5 9]
then
dedupe(a) = [5 3 6 4 7 9]

[b,ia]=unique(a,'first');
b=sortrows([b;ia]',2)';
b=b(1,:);
solved in one line !
nice problem
Hi, bainhome:
Cody is based on the 'current' version of MATLAB, not R2012b. Many functions are unchanged, but a few have changed (modified, new, or removed), including "unique".
You must add the 'legacy' flag to the list of arguments to preserve the behaviour of the "unique" function from R2012b and prior releases — refer to the documentation (link posted by Jakub Galecki).

if u know a specific function its too easy.
cool
