MATLAB: Removing repeated values from an array

array manipulation

Suppose I have an array [1.2 8 89 1.2 4 8 32 1.2]. Is there any MATLAB function that gives me the array without repeated values: [1.2 8 89 4 32]?!

Y=[1.2 8 89 1.2 4 8 32 1.2]
unique(Y)  % The result is sorted

%or

unique(Y,'stable')  % the result is not sorted

Hi,

There is an extra optional argument that will do that:

>> m=[1 6 2 8 9]; [Y,I] = sort(m,'descend')
Y =
       9     8     6     2     1
I =
       5     4     2     3     1
>>

a=1.2*(ones(4,1))
