What does diff(one inequality) do?

Hi, everyone, I saw a line of code: A=diff(B>=C), I am not sure what it does. Does it mean that, if B>=C, then do the differentiation between B and C? Hope someone with experience can help me answer this question. Thanks a lot.

Lets try it:
B = rand(1,11);
C = rand(1,11);
V = B>=C
V = 1×11 logical array
0 1 1 0 1 1 1 1 0 0 0
A = diff(V)
A = 1×10
1 0 -1 1 0 0 0 -1 0 0
So far everything behaves just as the GE and DIFF documentation explain.
Thanks a lot, Stephen, get it.
