How to locate and extract elements from a matrix?

Hi, I need to locate specific elements in each column of a matrix and print them in a new column matrix. For example if I have a 6x4 matrix
A = [a1 b1 c1 d1;
a2 b2 c2 d2;
a3 b3 c3 d3;
a4 b4 c4 d4;
a5 b5 c5 d5;
a6 b6 c6 d6]
I should locate some elements from the first column of matrix A, and print them into two new column matrices B and C. The first column of matrix A is a1, a2, a3, a4, a5, a6
My new matrix B should take these elements: a1, a2, a3, a4, so
B = [a1; a2; a3; a4]
After that I should define new matrix C, which will take elements a3, a4, a5, a6, so
C = [a3; a4; a5; a6]
This process I need to repeat for every column of matrix A. Does anyone have tips how to do this? Thanks!

You've accepted harjeet's answer so we'll assume that his code does the rules you gave above and the problem is now solved.

try this
clear all
close all
clc
A=randint(6,4,[1 100])
for i=1:size(A,2)
o=A(:,i);
B=o(1:4)'
C=o(3:6)'
end
