How can I run through an array and pick out certain values by condition

I have an array (let's call it events) of 19372x1. In this array there are values that are just one number above the previous value. I want to loop through this array and whenever there are values with only a difference of 1 between them I want to pick out the value right at the center of this "sub-array". For example, if my array was [690 691 692 693 694 678 679 701 713] then I want to have a result of [692 678 701 713]. How can I implement this in MATLAB?

Start by finding locations of ix=[false diff(events)==1)] then locate the discontinuities in those stretches. Then it's the median of the subsections. Since you'll be shortening the vector, you'll have to be careful to either work from the end forward on substitutions or build a new result in order to not change positions just found.

So how would I create these subsections to find the median?
