movmax - remove duplicated

Hello,

I am using movmax in order to find local maximum values on a very long vector.

i want to create a vector which will not include the repetitive number of the maximum value.

it means that if my vector is: y= [2,3,4,5,4,3,2]

and I use: movmax(y,3)

the result will be: 3 4 5 5 5 4 3

what I wish to get is that if there is repetitive maximum value it will show it only once:

the result will be: 3 4 5 4 3

how can I do that?

y= [2,3,4,5,4,3,2]; 
m = movmax(y,3); 
m([1,diff(m)]==0) = []; 

Answer 2

y = [2,3,4,5,4,3,2];
v = movmax(y,3);
out = v(diff([0,v])~=0);
