Hello
I have a vector of 1400x1 with several adjacent values (values with a difference of less than 1).
For example, my data looks like
A = [1 5 6 7 8 9 10 11 12 20 21 22 23]'
I'd like to delete the row that is adjacent to the previous one, so my expected outcome will be [1; 5; 20]
Any ideas on how to do this? I appreciate your help!

A = [1 5 6 7 8 9 10 11 12 20 21 22 23];
A([false,diff(A) == 1]) = []
A = 1×3
1 5 20

But since you said "a difference of less than 1" you'd want <1 instead of == 1
A([false;diff(A) < 1]) = []
Of course then your expected outcome is not right. Maybe you mean "a difference of 1 or less" in which case it would be
A([false;diff(A) <= 1]) = []
