I want to delete the element from a particular position in the vector as I have repetitive elements in that vector.

For example, I have

A =[1 2 3 2 5];

and I want to delete 2 from 4th position. Help me out

You might just want to use UNIQUE..

 >> b = unique(A) ;

b = unique(A,'stable');

Yes, I assumed 'sorted' as the outcome of removing the 4th element is a sorted vector, but I should have made this assumption explicit and mentioned 'stable.

Thanks for the answer, its working for this particular vector. But here the condition is bit different. I mentioned from a particular position because I can have the vector of type

A=[ 1 2 3 2 5 2]

now again, i want to remove only 4th element. So pl consider according to generalize vector. Thanks

 A(4) = []

if you want to remove only element #4.
