Lets say that I have these vectors
v1=[2 4 1 4]
v2=[1 3 3 4]
v3=[2 6 9 5]
and I wan't to find all the vectors that have any of these numbers
nmbr=[2 5 9]
which whould give med v1 and v3 How would i solve this?

any(ismember(v1, nmbr))
any(ismember(v2, nmbr))
any(ismember(v3, nmbr))
If true, then the vector has any of these numbers [2 5 9]

You can also do by combining v1,v2,and v3
v1=[2 4 1 4];
v2=[1 3 3 4];
v3=[2 6 9 5];
V = [v1', v2', v3']; % each column represents a vector
nmbr=[2 5 9];
p = ismember(V,nmbr);
result = find(any(p))
The answer is
result =
1 3
So v1 and v3 are satisfied
