Find rows where one column value matches with any value inside another array

I am new to Matlab, so please respond even if the question is trivial

I have a matrix. Lets say matrix is

A =[
    16     2     3    13
     5    11    10     8
     9     7     6    12
     4    14    15     1]

I have an array. Lets say array is

B = [3, 6, 15]

I want to find out all the rows of Matrix A where column 3 value of Matrix A matches with any value mentioned in the array B. In the above case output will be

ans = [
    16     2     3    13
     9     7     6    12
     4    14    15     1]

I don't want to use loop for this calculation. Is there any built in function which does this.

Thanks

This works:

A =[16     2     3    13
     5    11    10     8
     9     7     6    12
     4    14    15     1];

B = [3, 6, 15];

idx = ismember(A(:,3),B);
Result = A(idx,:)

Result =

      16     2     3    13
       9     7     6    12
       4    14    15     1
