How to delete previous values within a certain difference?

Hello.

I have a vector A (1571x1), and many values are adjacent, for example [1,2,3,4,20,21,22,35,36,37,38...]. I want to delete all the previous values with a difference of less than 10, and keep the biggest value in that continuous series. So my expected outcome will be [4,22,38...].

I have this code:

keep = false(size(A));
b = -Inf;
for i=1:length(A)
    if CLIMBDOWN(i) >= b
        keep(i) = true;
        b = A(i) + 10;
    end
end
A = A(keep);

but this deletes the values that comes after, so it keeps the smallest in that series (exp. [1,20,35...]). I have tried changing the 6th row of the code to -10, but the code did not run properly and did not delete any numbers.

Any ideas on how I can modify this? Or perhaps a different code that will do the job?

Thank you for your help!

You can do this

A = [1,2,3,4,20,21,22,35,36,37,38,50,51,52,53,54,57,70];
A = A(diff(A)>10)

A = 1×4

4 22 38 57
