How can i seperate columns by comparing the values of first row?

I have a martix

A=      0     1     0     0     1     1     1     1     1     1
     0     1     0     0     1     1     1     1     1     1
     0     1     0     0     1     0     1     1     1     1
     0     1     0     0     1     1     1     1     1     0
     1     1     0     0     1     1     1     0     1     1
     0     1     0     0     1     1     1     0     1     1
     0     1     0     0     1     1     0     1     1     1
     0     1     0     0     1     1     1     1     0     0
     0     1     0     0     1     1     1     1     1     1
     0     0     0     0     1     1     1     1     1     0
     0     1     0     0     1     1     1     1     1     1

where, in compare to first row i want to have two separate matrix as B with all values which will have A(1,:)==0 and C with all values which will A(1,:)==1

In other words,from this example i want to separate 1st, 3rd and 4th column in a separate matrix and others in another matrix.

Answer 1

[Andrei Bobrov]

t = A(:,1) == 0;
B = A(:,t)
C = A(:,~t)

Answer 2

[ahsan mahmood]

clc;
clear all;
A=[1 1 0;1 2 5;3 6 8;5 4 2];  
j=1;
k=1;
nn=size(A);
for i=1:nn(2)
    if A(1,i)==1
        C(:,j)=A(2:end,i);
        j=j+1;
    else
        B(:,k)=A(2:end,i);
        k=k+1;
    end
end
