Let me define first that: 'distance' is a vector (1 x n) and 'f' is a scalar (1 x 1). Example: distance = [1 10 5]; f = 2. The logical operator: distance > 2 would output: [0 1 1].
I want to say that if the output is NOT all zero, then do X. If the output is all zero, then do Y. How do I translate that to if-then statements?
Thanks for your help.

One approach:
if all(distance > f)
sprintf('All distances > %.1f',f)
else
sprintf('Some distances <= %.1f',f)
end
