how to save a matrix in a loop together whose size is changing?

I have a matrix A who is changing the number of columns and rows in a loop for example,

there are 5 iterations

for i=1:5
........
........
........
end

where

A(1)=[2 3 4];
A(2)=[1 2 3 4 5
      1 5 2 6 8];
A(3)=[2 1 4 5 6 7];
A(4)=[1 2 5 6 7 8
      2 3 9 4 3 1];
A(5)=[1 2 3 4 5 6 7 8];

in B i want to save all the values of A.

please help me.

You could put the matrices into a cell array:

B = cell(1,5);
for k = 1:5
    B{k} = A;
end
