Hi, I have a data for angle in degrees: deg=[10 10 270], and would like to calculate smallest change ie ans=(0 0 80)

Smallest change in angle between what and what?

10, 10 and 270 are true degrees (ie direction of a pointer), so at 1st min was pointing 10deg, 2nd min pointing 10deg, 3rd min pointing 270deg. I'd like my answer to display 0deg for first min, 0deg for second minute (diff btw 10 and 10) and 80deg (diff btw 10 and 270 deg)for 3rd min(not 260 degrees)

angles = [10 10 270];
changes = mod(diff(angle), 180)

80 degrees is not the difference between 10 and 270. 100 degrees is the difference between 10 and 270. You have to pass down through the 10 to 0 degrees and then travel another 90 degrees to reach -90 degrees = 270 degrees, and that is a total of 100 degrees.

I had added the 0 because initially you wanted 3 outputs for 3 inputs.
