dbscan(A)
Error using dbscan
Expected X to be one of these types:

single, double, logical

Instead its type was duration.

As with your earlier question, convert your durations to numeric values using minutes. You can later convert it back to durations also using minutes.
A = duration('00:01:01')
A = duration
00:01:01
B = minutes(A)
B = 1.0167
C = minutes(B)
C = duration
1.0167 min
C.Format = 'hh:mm:ss'
C = duration
00:01:01
