accessing the first column of each cell ?

lets say I have a cell matrix that was created with 2000 cells each is a 6 by 7 matrix . I want to acces the 7th column of each of these cells and store them in 200 matricies as well. How can I do that ?

Next, I want to solve a linear equation with the right hand side being the 2000 vectors that I have exracted and the left hand side being the 6 by 6 matricies, and of course i should obtain 2000 values for x's.

Any help is appreciated please

Only first part is answered:

c=cell(1,2000);
for i = 1:2000  % -> numel(cellmatrix)
c{i}=cellmatrix{i}(:,1);   % change 1 to 7 if you want to extract 7th column
end
celldisp(c) % -> first columns extracted from 2000 cells
