Test if vector elements are a subset of another vector. % subset of numerical vectors a = [2,3,4,5,6] b = [3,5] % is 'b' a subset of 'a' ?all(ismember(b, a)) 1 % True (yes is subset) % subset of logical vectors % use find when comparing logical index vectorsx=[1,2,3,4,5,6,7,8] idxA= x > 3 0 0 0 1 1 1 1 1 idxB= x > 5 0 0 0 0 0 1 1 1 % is logical vector idxB a subset of idxA ? all(ismember(find(idxB), find(idxA))) 1 % True (yes is subset) |
