Want to find a specific column of needed data

I have a matrix of B= [ ]4*25 data bits, and i have another variable which consist of one of the column of B. How can i find specific column with its number?

e.g. B=[1 1 0 1; 1 1 1 0;..........0 1 1 1]; and i want to find S=[1 0 1 1] in B.

Answer 1

[r c] = find(ismember(B(:,1), S, 'rows'))

i got this answer when i tried above method: r =

     1
     2
     3
     4

c =

     1
     1
     1
     1

but if i know only column number then also its fine... Its expected that find S in B without using for loop.

Have you tried using ismember? I believe you can use a combination of MATLAB functions find and ismember.

 find(ismember(M,X),dim)

The "dim" should be columns. So you can take a transpose of your matrix.

need to take transpose of B as well as S to get proper answer.
