MATLAB: Need help writing an if statement involving vectors. Total mental block :/

Question

I have a vector:

A=[14 13 12 11 10]

And I'm given another vector B that's the same length of A, and contains any numbers.

I need to write an if statement determining if this vector B contains the same numbers as A (even if the numbers are arranged differently than in A)

NOTE: INCORRECT SYNTAX, but here's the idea

if B==A

disp('B is equal to A')

else

end

Answer 1

I think you could use the ismember() function to do what you need. It'll return a vector of ones and zeros, so you would just have to check the returned vector for any zeros.

EDIT: if you use all(ismember(A, B)), I think that'll do the trick.
