Use intersect(). See the first example in the help:

Intersection of Two Vectors
Define two vectors with values in common.

A = [7 1 7 7 4]; B = [7 0 4 4 0];
% Find the values common to both A and B.

C = intersect(A,B)
C =

       4     7

Image Analyst, Thanks for your reply.

But i have tried this, I have attached a mat file of [1x9] cell array which has my data. I am trying it but i am not successful so far. Can you kindly give some time for this.? I will be thankful.

That is a 1 row by 9 column cell array. Each cell has a column vector in it of different lengths.

What two columns do you want to compare? Like column (cell) 3 with column (cell) 7? Or what? Why can't you just get the contents and do what I said

s = load('cell_data_rx_ids.mat') % Load into structure.
cell_data_rx_node = s.cell_data_rx_node; % Extract from structure.
column3 = cell_data_rx_node{3} % Extract column 3
column7 = cell_data_rx_node{7} % Extract column 7.
% Now find intersection, the common values.
commonValues = intersect(column3, column7)
