Lowest differential in data group

hi, i want ask about how to find out the lowest difference in data group? if highest difference in data group use peak2peak, how if the lowest one ? thanks for your attention

[Torsten]

What according to your definition is the "lowest difference" in a = [ 1 5 6 17 ] ?

1 - 17 = -16

or

5 - 6 = -1

?

Best wishes

Torsten.

Apply the same function to -A (A is your matrix)

[Denny Bhatara]

 peak2peak(-a)?

Ex a = [ 1 5 6 17 ] If i want find out the highest difference is b=peak2peak(a) And then b = 16 How i want find out lowest difference?
