Concatenating a signal given its segments' limits

Hello there:

I have this vector (a small sample) :

ww =

10 15

16 22

33 44

45 50

51 60

70 80

These are intervals that delineate a biomedical signal in segmants. For instance segment#1 delineates the signal beteewn the samples 10 and 15, segmnent#2 delineates the signal beteewn the samples 16 and 22. Segmnent#3 delineates the signal beteewn the samples 33 and 44. And so on. We want the segments whose distance is less than N samples to be concatenated. For isnatance for N=1 the result would be:

ww_new =

10 22

33 60

70 80

Thank you for your time!

Regards

ww = [
    10    15
    16    22
    33    44
    45    50
    51    60
    70    80
    ];
N = 1;

to_keep = ww(2:end,1)-ww(1:end-1,2)>N;
to_keep = [[true; to_keep] [to_keep; true]];
ww_new = reshape(ww(to_keep),[],2)

ww_new = 3×2

10 22 33 60 70 80
