how to extract matrices from a cell based on column sum of each matrix?

I have a cell A which contains 1806 matrices. each matrix is a binary matrix with 7x3 size.. I want to extract only those matrices from A in which sum of each column is greater than equal to 2 for example A contains matrix

A{1}=[1  0 0;
      1  0 0;
      1 0 0;
      1 0 0;
      1 0 0;
      0 1 0;
      0 0 1]
A{2}=[1  0 0
      0  0 1
      0  1 0
      0  0 1
      0  1 0
      1  0 0
      0  0 1]
A{3}=[0  1 0
      0  0 1
      1  0 0
      0  0 1
      1  0 0
      0  0 1
      0  0 1]
A{4}=[0  1 0
      0  0 1
      1  0 0
      0  0 1
      0  1 0
      1  0 0
      0  1 0]

I want to multiply these matrices with another cell of matrices but only those matrices for which sum of each column is >= 2. I got the idea of applying this but how to continue the loop if A{i} is not satifying the condition

for i=1:numel(A)
  for =1:numel(B)
     if all(sum(A{i})>=2
      C{i,j}=bsxfun(@times,A{i},B{j})
  end
end

how to store values of C for which A is according to condition.? the complete code is below

tic;
no_of_machines=7;
no_of_cells=3;
No_of_Parts = 6;
move_cost=[0.12;0.12;0.12;0.12;0.12;0.12];

P1=[1  0  0  1  0  1  1;1  1  0  0  1  0  1];
P2=[0  1  1  1  0  0  1;1  0  1  0  1  1  0];
P3=[1  0  0  1  1  0  0;0  1  1  0  0  0  1];
P4=[1  0  0  0  1  0  1;0  1  0  1  0  1  0];
P5=[1  1  0  0  0  1  0;1  1  0  0  1  0  1];
P6=[0  1  0  0  0  1  1;1  1  0  1  0  1  0];

P = [P1;P2;P3;P4;P5;P6];
z = [size(P1,1) size(P2,1) size(P3,1) size(P4,1) size(P5,1) size(P6,1)];
c = [0 cumsum(z(1:end-1))];
a = allcomb(1:z(1),1:z(2),1:z(3),1:z(4),1:z(5),1:z(6));
n = size(a,1);
B = cell(1,n);
for i=1:n
    B{i} = P(c+a(i,:),:);
end

t = 0;
for k = 0:(no_of_cells^no_of_machines)-1 
    s = dec2base(k,no_of_cells,no_of_machines);
   if length(unique(s))==no_of_cells
        t = t+1;
        CELL(t,:) = s-'0'+1;
    end
end
CELL = CELL(1:t,:);
combination_array=num2cell(CELL,2);

for c=1:numel(combination_array )                           
    R=1:numel(combination_array{c});
    Z = zeros(R(end),max(combination_array{c}));
    Z(sub2ind(size(Z),R,combination_array{c})) = 1;
    A{c}=Z; 
end

I want to multiply A and B where B is 1x64 cell and A is 1X1806 cell. this gives total of 64x1806 cell.but I want to multiply B with only those A which fulfill the condition of column sum.

[Walter Roberson]

mask = cellfun(@(M) all(sum(M,1)>=2), A);
output = cellfun(@times, A(mask), B(mask), 'uniform', 0);

[summyia qamar]

what is M? its giving error of index exceed matrix dimension
