Finding certain numbers in vectors

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?

Answer 1

[Wan Ji]

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]

[Wan Ji]

So you see the answer is true, false, and true. v1 and v3 are satisfied

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
