Q:

How do I extract those rows of a matrix whose elements of a column are present in an array? 

Say I have a matrix, M:
9.89E+10    3.12E+10    29
8.88E+10    8.16E+10    9
9.97E+10    8.31E+10    22
8.10E+10    6.55E+10    94
2.17E+10    8.11E+09    53
6.34E+10    8.84E+10    54
5.69E+10    7.07E+10    8
9.23E+10    8.24E+10    38
8.88E+10    5.81E+10    27

And I have another array, A:
A=8.88E+10, 9.23E+10

I want all the entries in M that contain all the entries in A. That is, my output should be a matrix, N:
8.88E+10    8.16E+10    9
9.23E+10    8.24E+10    38
8.88E+10    5.81E+10    27

I can do this using a code like:
count=1;
for i=1:size(A,1)
    for j=1:size(M,1)
        if M(j,1)==A(i,1)
            extracted(count,:)=M(j,:);
            count=count+1;
        end
    end
end

But I guess there could be a one liner code in MATLAB to do this.  Is there any? 

A:

One Liner Solution
N = M(sum(ismember(M,A),2)>0,:);

Explanation

The ismember function generates a binary matrix of the same size of M, which contains 1 for each value in M which exists in A and 0 otherwise. 
We use sum function to sum each row in that matrix.  rows which sum up to a value which is bigger than 0 are rows which contains values from A.
Last, we generate the out matrix by taking all the rows from M which fits to the constraint from previous stage. 

Result
N =

8.88E+10    8.16E+10    9
9.23E+10    8.24E+10    38
8.88E+10    5.81E+10    27
