Accessing Cell Array elements

I have a cell array which consists of 10 cells. Each of the 10 cells has a matrix of size 250 by 2. I need to access the second column of each of the matrix of size 250 by 2. How can I access it . Please help. I'm using the following method :

where length(t) =250 and azi_all is the 1 by 10 cell

c = zeros(length(t),1);
for cc = 1 : 10
  zenith{cc} = c;
end

for i = 1:10

    zenith{i} = 90 - azi_all{1,i};

end

When I'm using the above code both the columns are being modified as per the (zenith{i} = 90 - azi_all{1,i};) equation whereas I need only the value of the second column to be changed. Please suggest some way.

I'm not sure I understand all the details of what you are trying to do, but I can show you with an example how to modify the second column (in this case, setting all the values to zero):

C = {rand(10,2),rand(10,2)};
C{1}(:,2) = 0;

disp(C{1})
  0.1622         0
  0.7943         0
  0.3112         0
  0.5285         0
  0.1656         0
  0.6020         0
  0.2630         0
  0.6541         0
  0.6892         0
  0.7482         0
